Liverpool have been warned about Xherdan Shaqiri's attitude by one of his former teammates.

Charlie Adam played alongside Shaqiri at Stoke last season as they were relegated from the Premier League before joining Liverpool this summer.

He marked his debut by scoring a superb overhead kick in a 4-1 pre-season victory over Manchester United.

Adam described Shaqiri as a "top player", who deserved to be at a club of Liverpool's stature, but questioned his commitment at crucial times in Stoke's relegation fight.

"He's a big player, at times he did well for us," Adam told the BBC. "But in critical situations, I felt tracking back and what we needed for the team in a relegation battle just wasn't there.

"He has got it in him, but he probably knew we were going to get relegated, he was going to the World Cup and had this big move - this move was probably done three, four months ago.

"He is a match-winner, but at times it was difficult to play in the same team. The manager would let him get away with certain things."

Adam said Shaqiri could soon start to grow impatient if he struggled to hold down a first-team place.

"He might get frustrated at not playing as much as he wants - it's how long he waits and what (manager Jurgen) Klopp does with him," the Scot added.
