The Liverpool boss admits he perhaps should not have asked so much of the defender.
Liverpool manager Jurgen Klopp has admitted that he is crossing his fingers that Joel Matip's injury is not too serious after the defender limped off in the friendly win over Wigan Athletic, as quoted by the Liverpool Echo.
Matip, who signed for Liverpool on a pre-contract agreement in February, started the Reds pre-season clash with the Latics on Sunday afternoon.
The 24-year-old has suffered injury problems in his foot in the past and began feeling some pain in his foot in the past fortnight after the start of pre-season.
Klopp decided to test the former Schalke man out in the 2-0 victory, but admitted that it may have been the wrong call to ask so much of the Cameroon international so soon.
The Liverpool boss hopes that Matip has not suffered any lasting damage from the latest issue, and stressed that the defender is generally in good condition.
Klopp said, as quoted by the Echo: "I hope it’s only a minor problem. He said he’s had it one or two times already. Joel gets better and better and better, you can see it. It’s not too seriously, hopefully.
"It’s the foot he had problems with in the past and then he had a little bit of pain when pre-season started because of the intensity. He’s used to it. Hopefully it is like this because everyone can see he’s in a real good way. I think tomorrow he’ll rest then he can go again.
"We had to make the decision of Joel or Dejan [Lovren], who has to play the whole 90 minutes? We decided Joel but for him it was a little bit too much today."
Any lasting damage to Matip would be particularly troublesome for Liverpool, given that Mamadou Sakho and Joe Gomez are already on the sidelines.
