Sky Sports pundit Andy Walker believes Celtic manager Ronny Deila is on the brink of losing his job after the Scottish Cup semi-final defeat to Rangers.Deila refused to comment on his future after watching Celtic lose 5-4 on penalties to their city rivals at Hampden Park on Sunday. The Norwegian, who was appointed as Neil Lennons successor in June 2014, has come under fire from certain sections of the Celtic support this season, with the clubs failures in European competition a particular reason for their disharmony. Highlights of Celtics Scottish Cup semi-final defeat on penalties to Rangers at Hampden With Rangers set to join the Scottish elite from next season following their promotion from the Scottish Championship, Walker feels Celtic will part company with Deila as they attempt to maintain their dominance of the top flight. When asked what the defeat may mean for Deila, Walker told Sky Sports Now: It leaves him on the brink. I dont think he can survive this, I dont think theres any appetite to get rid of him immediately, but you have to look at Ronny Deilas time overall as a Celtic manager. Rangers celebrate after winning the penalty shootout against Celtic What has he done? Where are the big victories? Where are notable victories that he has come up with? Would any Celtic supporter look at this current group of Celtic players and think they would get through the Champions League qualifiers, if they as expected go on and secure the title for the fifth time? I dont think this is a group of players that can get through a Champions League qualifier and thats really where Celtic want to be. They are currently being compared to the likes of Aberdeen and Hearts. Rangers will be up next season and I think Mark Warburton is right, he is a smart guy and theyll need a lot of investment to compete with Celtic and Aberdeen. Ronny Deila says Celtics performance was not at the level he expects after they lost to Rangers I dont think he is fooled, he has got the basis of a really good team, but the biggest difference for me was the strength and depth. I think Celtic have a stronger squad, but I dont think they utilised their players very well and I think that is one of the main reasons that Ronny Deila wont survive this. Walker also accused Celtic captain Scott Brown, as well as a number of other first-team players, of being unfit and believes Rangers superior fitness was a telling factor at the end. Brown out of form and unfit says Andy Walker I think you have to look at Celtic overall in 120 minutes, they were not good enough, added the former Celtic and Scotland striker.When youve got players like Scott Brown, who are completely out of form and unfit, and he still gets a place in the team, then I think thats a problem. Charles Paterson and Andy Walker reflect on the thrilling Old Firm clash in the Scottish Cup semi-final You look at Celtic overall, youve got Tom Rogic, who came on as a substitute and made a good impact, Kieran Tierney played well, Erik Sviatchenko played well, but apart from that you are not really giving plus marks to any other Celtic player. For me, Rangers deserved their win. They played a lot of good football and they were a fitter side than Celtic yesterday, that was telling.

The Oilers come in having lost five in a row (0-4-1) and 16 of their last 20 games, dropping a 2-1 decision to the Vancouver Canucks on Tuesday.LUBBOCK, Texas -- Texas aims for its first road win this season when the Longhorns face Texas Tech on Saturday.The two teams have identical records, but the Red Raiders (2-3, 4-4) have won one game away from Lubbock -- after losing two earlier this season. They beat TCU last week in Fort Worth on a field goal in the second overtime.Texas coach Charlie Strong says his players need to summon a home-game mindset for the Longhorns (2-3, 4-4) to get their first road win in Lubbock.So how good you feel when youre at home, thats the same feeling that we have to take when were on the road, even though its a different atmosphere.Texas biggest challenge will be stopping Texas Tech quarterback Patrick Mahomes, who leads the nation in passing yards (3,519) and total offense (471.3 yards per game). The junior is still recovering from an injury to his passing shoulder in late September. He fell on it painfully on a rush that set up the winning field goal at TCU.Texas Tech coach Kliff Kingsbury says Mahomes shoulder has steadily improved and that he gets daily treatments.I think it scared him, the fourth-year coach said. He landed right on it. Im sure there was some pain, but he sounds like he will be able to practice almost a full week so that should help.TCU kept Mahomes contained inside the pocket for most of the game, holding him to a season-low 206 yards passing. The team had a season-low 345 total yards and was held to its fewest points since a 20-10 win over the Horned Frogs in 2013.Thats whats got to be critical for us, not to let him outside, Strong said.A few more things to look for when Texas Tech hosts Texas:TEXAS RUSHINGDOnta Foreman, second in the nation in rushing yards (158 ypg), got two TDs and 250 yards on 32 carries in the Longhorns 35-34 win over Baylor last week. Thats more than the team is averaging per ggame (226.dddddddddddd5 ypg). The performance made Foreman Texas first 1,000-yard season rusher since Jamaal Charles in 2007. Texas Tech has given up 300-plus yards rushing three times this season and is allowing an average of 213.8 yards. He runs with everything he has, Texas offense lineman Connor Williams said.THIRD DOWNSThe Red Raiders lead the nation in third-down conversion (57.8 percent), getting 74 first downs on 128 third downs. That is way better than the Longhorns who are 58th in the nation. Texas has gotten 52 first downs on 126 third-down attempts (41.3 percent). Kingsbury said a lot of the success is due to Mahomes abilities. Pat does a tremendous job of understanding the down and distance, he said. If its not there find a way to get it with your feet, so its a credit to him on more than the brilliant third down play calling that goes on.SMACK TALK BACKLASH?Texas DE Breckyn Hager apologized, and Strong chastised him, for a comment he made to TV reporters Monday, telling them the mission for the Longhorns defense was to injure that quarterback, referring to Mahomes. Some of Texas Techs faithful, in social media posts, wrote that the apology was not accepted. The comment could make for some added tensions between the teams.PENALTY REBOUNDPenalties have hurt the Red Raiders all season. They are 124th in the nation with 8.75 penalties per game. But against TCU Texas Tech had just one -- a 5-yarder. That hasnt happened since 1992. Can they keep it up against the Longhorns? They made their decision to play disciplined, Kingsbury said. That was the focus.---Follow Betsy Blaney on Twitter at www.twitter.com/betsyblaney---AP college football website: http://collegefootball.ap.org ' ' '
