The former FC Twente star insists he'll get better.
"My first game has taught me we have to create a lot of chances!" Fer told the Pink 'Un. "But no, I think it's a really physical game here in the Premier League and a lot of up and down, up and down, defend and then attack. So it's good for your conditioning and I have to work on that.
"But I'm glad I played 90 minutes. In Holland it's less physical and powerful but I think I have to work on that conditioning and I will be better in the next game."
