Tottenham legend Gary Mabbutt believes his former side can still push for a place in the top four if they show the same commitment they did against Arsenal yesterday.Spurs lost the north London derby 1-0 thanks to an early Tomas Rosicky goal, but dominated the game with many feeling they were unlucky to lose.The performance seems to have been a positive reaction to manager Tim Sherwood’s comments following a 4-0 defeat at Chelsea, in which he branded the players gutless and lacking character.The defeat to Arsenal has moved them seven points off the top four but Mabbutt – a UEFA Cup and FA Cup winner in 16 years at White Hart Lane – thinks they can take positives from the game.He told talkSPORT: “Arsenal defended excellently – everything we tried to create was snuffed out.“We didn’t create too many clear-cut chances which I’m sure they’ll be working on but the supporters and the manager will be happy with what the players have shown.“If they maintain that sort of commitment until the end of the season then hopefully we can still pushing for a spot in the top four.”Tottenham have not qualified for the Champions League since 2010/11, when they made the quarter-finals in their only appearance in the competition to date.
