In the first round of the Champions League league phase, Liverpool hosted Atletico Madrid, and Gakpo was not included in the match squad. Iraola explained the reason for Gakpo's absence in a pre-match interview with TNT Sports.

Iraola said: "Cody (Gakpo) had some problems with his adductor at the end of the match against Ipswich a few days ago, on both sides. But there is nothing particularly serious."
"This is not a real injury in the true sense. But we don't want to take risks. I think it is reasonable to let him rest, and hopefully we can help him recover. If he cannot make it this weekend, we will aim for a return next week. However, I think he even has a chance to be available for the weekend match."
