Manchester City defender John Stones believes that something can still defeat them in their quest for silverware this season: fatigue.

It is no surprise to hear Stones talk about fatigue, because City are still in four competitions this season.

The club has a chance to win the League Cup, if they can get past Bristol City in the semi finals. They are the runaway leaders in the league, and still in the Champions League and FA Cup.

It will take incredible management of the team's squad for Pep Guardiola's City to emerge victorious on more than one or two fronts.

Stones said: "The four competitions we are still in, the amount of games compared to some other teams, you know it takes a toll, no matter how much you rotate the squad.

"We obviously wanted to go unbeaten through the whole Premier League season. I'm sure every team does, but it's such a difficult thing to do.

"I think sometimes you have got to hold your hands up and say: 'we gave it our best shot' - which we did."
