Emre Can has claimed he may sign a new contract with Liverpool despite Juventus’s belief they will land the midfielder on a free transfer this summer.

The Germany international is out of contract at the end of this season having resisted several attempts by Liverpool to extend his four-season stay. Juventus have been repeatedly linked with the 24-year-old and are confident he will move to Turin on a proposed five-year deal.

But Can, who could sign a pre-contract agreement with the Italian champions this month, maintains his future is undecided and that negotiations are ongoing with his current employers among others.

“My agent is looking after everything but I am here until the summer,” he said. “I haven’t signed anything with anyone. I am talking with everyone. Of course I am talking with Liverpool. Why not? I still have a contract here. It is an amazing club.

“What can I say? My agent does the rest. I just concentrate on the scene, on my performance and the football. I will give everything for this team.”

Can produced a commanding performance on Sunday when Liverpool ended Manchester City’s 30-game unbeaten run in the Premier League with a thrilling 4-3 victory. The midfielder, who had to be withdrawn in the second half because of illness, insists it was one of the finest displays of Jürgen Klopp’s reign.

He said: “It was unbelievable. I think it was the best game in terms of how I saw it. Look at how we pressed. We played against Manchester City, you can’t forget that.

“We were always on the front foot, everyone pressing and everyone did a brilliant job. We have played a lot of games that are very good but this one? I don’t know how many kilometres we ran. Look at how we pressed. It was one of the best we have done, for sure.”

Liverpool remain 15 points behind Pep Guardiola’s leaders in the Premier League but Can believes Sunday’s performance can be a statement of intent towards their rivals in the Champions League. Klopp’s side face Porto in the last 16 next month and are on an 18-game unbeaten run – their last defeat was against Tottenham, 4-1 at Wembley on 22 October.

“Against Manchester City we played brilliant,” Can said. “If teams saw us playing like that they will give us a lot of respect and we will take a lot of confidence from it.

“We didn’t have to pick one player out against Manchester City. Every single player performed and did an amazing job. Sadio Mané, Roberto Firmino, Mo Salah scored the goals but Andrew Robertson, Joël Matip, Joe Gomez, they all did an amazing job. If teams watch this performance they will think: ‘Oh wow!’ They will see we are a strong side. But this is just one game, just three points and we have to keep going.”

Can’s midfield colleague Georginio Wijnaldum believes Liverpool can be genuine title rivals to City providing they acquire more ruthlessness and consistency.

He said: “There were some difficult games for City but they still scored and killed the game. That is something we didn’t do. Even in this game we gave them a chance to come back. That is the biggest thing we have to change if we want to compete with teams like City.

“I don’t want to say the difference is not big because they show it every game, and even in the games they did not play very well they won. That is the step we have to make to compete for the title.”

Liverpool, meanwhile, have confirmed Rhian Brewster suffered an ankle sprain and ligament damage in the under-23s’ game with City on Friday. The 17-year-old striker was taken off on a stretcher in the 3-2 defeat after a heavy fall and will require further tests this week to determine the full extent of the injury.
