Manchester City are worried about the state of the Wembley pitch ahead of their game against Spurs.
City know their game at Spurs will be at Wembley, as the club's new stadium is not ready.
But there are two NFL games taking place before that clash later in the month, while the Wembley pitch is already showing signs of wear after ONE American football game.
City are concerned the impact such a pitch would have on their players, with an increased risk of injury a serious possibility.
Spurs will hope that Wembley officials can get the pitch in order before the game.
