AS Roma chief Monchi says Javier Pastore will need time to settle.

The midfielder arrived in the summer from PSG.

Monchi also insisted Robin Olsen would prove his quality as a replacement for Alisson after his move to Liverpool.

He saidm, “Javier worked to be in good shape and the Coach worked on his mentality too. He is convinced that he can do well in that midfield role and I am sure he'll have a good season. Quality players can play anywhere.

“Alisson is one of the top five goalkeepers in the world. We tried to go for experience and chose Olsen. He has a lot of experience, played at the World Cup and you can see he is good with his feet in training."
