Manchester City boss Roberto Mancini is angry not to have added to his squad this summer.

Following last season's heart-stopping triumph, City were in the perfect position to reinforce. Instead, he fears they are standing still.

"When you win something it is important to improve," he said.

"But you should not buy new players 10 days from the end of the window. It should be two months.

"The championship finished on May 13. You needed to buy players before now.

"Now it is difficult because there are some teams who can't sell their players because they don't have time to buy anyone else.

"The next 20 days is very difficult in the market."
