Liverpool defender Martin Skrtel has revealed that his current knee injury is not a serious one.

The Slovakian centre-back missed out on his international side's friendly against Romania due to the knock, but said that it is unlikely to keep him out for a sustained period of time.

"I stretched ligaments in my knee. Luckily it is not a serious injury," Skrtel wrote on his official website.

"I hope it is not a serious injury, though, and I want to be back on the pitch as soon as possible. can basically run but it hurts when I kick the ball. I can feel the pain in the back of my knee. It is not one of the major muscles but it is still not very comfortable.

"I spoke with Mr [Jan] Kozak, who is a new coach of Slovakia, and I also spoke with the medical staff and we agreed that it would be better when I stay in Liverpool."

Skrtel's future has been the subject of speculation this summer, with the 28-year-old recently claiming that he had "alternative" options to choose from, after reported interest from Napoli.
