I don't think Leicester can able to fight for the title in this season. They are not winning against big teams. Although they have won by a huge margin against Man City. But they lost against Liverpool and Man United. They need a stronger team to fight for the title. They need some world class striker. Their team is good enough. But I don't think it's the right team to win the title.
Despite yesterday's loss I think Leicester are playing very great. They have defeated Man City and Arsenal this season , plus United game is from last season. Talking about defeat against Liverpool , I would say it is hard to go against a side with experienced coach and they were aware about the problems going ahead in the game. Regarding lack of world class striker in Leicester, I want to ask you isn't Vardy not enough to be a "world class striker". He has been scoring around 20 goals every season for Leicester , last season I guess he was top goal scorer of last season. I think he is but sometimes opponents are aware of the threat and Liverpool did well to handle Vardy.
PL is a long race and anything could happen. Right now they are 4th and they are not playing that bad.
