He could miss more than a month if, as expected, his country progress to the latter stages of the tournament and, while Klopp admits he does not have a like-for-like replacement, he does have other options.

"He's a winger, so a very offensive player, outstanding player, very good, can play in the half-space, can do everything," the German said.

"If we had five other wingers to replace him already then we cannot have the team we have in this moment, with the atmosphere we have in this moment where everybody feels he is really important.

"You cannot have everything, so we decided to do this. Sadio's away and we have to find solutions.

"They can be, under very specific circumstances, in the transfer market, but if not then they are in the squad.

"We have been a little bit unlucky with injuries in the wrong moments but we still can play different systems and a lot of our players are really versatile and that's what we have to use.

"For this the players need to be open and I'm sure they are open for this.

"It's another sign for a kind of confidence: if you think the only system we can play is this system, that's not like it is, but we need to really show this."

Klopp's side have an extra day to prepare for the visit of Stoke compared to their rivals, who play Boxing Day, and, while the Reds boss is used to a winter break having managed in Germany, he would not want to have a break at this point with his side in the form they are.

"The good thing with having no break is you don't feel like you need a break," he added.

"So in Germany it was always like, 'Two weeks to go and then we have a break', but here nobody is in this mood.

"Everybody's on fire, we are all on the track, and that's a really good thing."

Tuesday will see the return to Anfield of Joe Allen for the first time since he left in the summer.

The Wales midfielder could not hold down a regular place under Klopp despite some influential performances but the Liverpool boss has no regrets about allowing him to leave as it was for the player's benefit.

"Do we miss Joe Allen? Yes. Nice guy, unbelievably strong player, but it was kind of a common decision," he said.

"We had some conversations and it was what I could guarantee, not that Joe Allen asked me, 'How many games will I play?'

"But it was clear after the last one, two years not being a fixed player all the time.

"We all knew about his quality and when you see him playing now we are all really happy for him that he scores that many goals and he has had this big impact for Stoke.

"That's how it is in life. You can't have everything. We couldn't have everything.

"I'm not sure that it would have been that easy for him (here) - it's not that he doesn't have the quality, but it's about having one option more or not and using it for this or that system.

"He plays a little bit more offensive (for Stoke) than he probably would have played for us. Joe Allen is for sure an outstanding player. I would say we need to keep an eye on him."
