Frank Lampard doubts Mauricio Pochettino can turns things around at Chelsea quickly.

Chelsea announced the appointment of Pochettino on Monday, a day after a disappointing season finished with the Blues in 12th position.

“Standards sounds a really simple word but it’s so relevant to this club at the minute,” said Lampard.

“Standards collectively have dropped, I can be honest about that, particularly as it’s the last game, I might not see some of them that much anymore anyway.

“The standards for a club like Chelsea have to be at a maximum or you won’t be physically competitive enough. Or you won’t get to play at a high level or a high speed like the Premier League demands.

“If you’re not together in the dressing room, and you’re not vocal in the dressing room driving each other and competitive because I want your place and you want mine and all of those things – any top team has to have that.

“At the minute, when I came in, very quickly I could see that wasn’t there enough. I think that’s something needed and of course a very good manager will help that. But everyone in that needs to take responsibility, players and club alike.

“Can it be turned around in a year? I don’t know that. It’s hard to say. This league is tough and it’s get more challenging every year, everyone is trying to move forward. I wouldn’t want to put a time-limit on it.”
