Ferguson knew the importance of winning even small trophies. Mourinho has always targetted the league cup when he first arrives at a club because he knows the importance of winning a first trophy. Every City fan can speak to how the air around the club changed after the FA Cup win.
I think when Pochettino sits at home watching the last MOTD of the season, big glass of malbec in his hand, he'll regret saying the league cup was not a real trophy and having his team play like they did last night.
This is a man who's been managing for 8 years and has never won anything.
This is the manager of a club whose only trophy in the last 26 years was the League Cup he thinks they are above.
He's made a big mistake yesterday IMO, thrown away by far his best chance of winning silverware at Spurs.
