West Ham boss Manuel Pellegrini admits their signing spree brings with it new management problems.

But the Chilean says he would rather have “one of the most difficult" tasks for a manager than a team that picks itself.

Pellegrini, who makes his league bow as Hammers manager at Liverpool tomorrow, said: “Maybe it is one of the most difficult things for a manager to keep them all happy, because all of them want to play and, with better players, more problems.

“But, for me, it is more difficult if you don't have players. When you just have 11, there would be no problem – you'd have the same starting XI every week.

“But they all know that if, during the whole season, you don't have a strong squad, it is difficult to be successful.

“For me, as a manager, it is easier to have more good players, and some of them must wait, but to have that option to change.

“We have two players in each position and they must work in a competitive way between them. Then I make the decisions on who plays."
