The Holland attacker says the team is still coming together after major changes made over the summer market.
He told Premier League Productions: "I think it's always been difficult when new players come in to adapt to the team. But I think now when we have a lot of new players, sometimes it's difficult when you change the team.
"We lost also a lot of players who were here (for) a long time. We were together for a few good years now. So, some players left, Lucho (Luis Diaz) left, Darwin (Nunez) left, Jarell (Quansah) left and Harvey (Elliott) left as well. Then you have to replace them and new players come in and you need to make it fit. I think that's going well.
"We try to get to know each other every day better and better again. It's also a little unfortunate with Alex (Isak), who didn't really have a pre-season. It's all these things together - but I think we will find a way forward."
