"I always go back to the pre-season," Cole told Sky Sports.
"I really don't think the team had a great pre-season in terms of the Covid stop-start, players catching Covid. They missed a big chunk of training.
"I think next season will be great to see the team have a good pre-season, understand the style and philosophy of the manager and then hopefully really click and gel.
"This season there's been moments in games they've been brilliant, they've been great to watch.
"Hopefully they can solidify that and come again strong. Of course, you talk about Haaland and what quality he has… but I'm happy with Werner, thank you."
