The on-loan Manchester United striker has found several former teammates at his new club.
He said, “(Kwadwo) Asamoah is a good lad. He didn't say much but I've found him chattier! He's a nice guy and I'm pleased he's doing well.
“(Samir) Handanovic is a leader. He has his say before the match. He encourages you and that's good for the group.
“That's important and I know Lukaku too from Manchester. We chat a lot, we hang out and have dinner together.
“It's great, he's a mate. I also know (Antonio) Candreva as we spent some time together at Udinese.
“I want do well and want to win trophies here. We have to fight for silverware. The key thing is team spirit as that makes the difference.
“If we're all united then we can win lots of trophies."
