"We have a lot of games so with Mascherano and Aquilani leaving we need quality players for the team because for the next six months we will have a game every four days," said the Danish midfielder.
"It is important for a club who wants to play at the top of the Premier League and fighting for the Europa League to have strong players.
"I hope after the international break we can come strong again and pick up a lot of points up in the coming months."
