Xherdan Shaqiri has hit back at claims made by Charlie Adam which questioned the Liverpool winger's professionalism during his time at Stoke.
Following Stoke's relegation from the Premier League in May, Adam said Shaqiri "never turned up" for the Potters in important moments and claimed then-manager Paul Lambert would allow his former team-mate to "get away with certain things".
Shaqiri, who joined Liverpool for £13.5m in the summer, has refuted Adam's claims and suggested the Stoke midfielder may be jealous of his move to Anfield.
"I think it's just frustration maybe or jealousy because I had a good move," Shaqiri told the London Evening Standard.
"I was surprised that he spoke like this about me but that is sometimes the character of a player.
"I know what he said was totally wrong because at that time I played there - especially when times were hard - I was there and I was scoring a lot of goals.
"I was one of the only ones who helped the team with goals in difficult games and he was that guy who took the red card in [important] league games (against Everton) and missed a penalty (against Brighton).
"I don't have to prove Charlie Adam or some people that are speaking about me wrong.
"I'm just a player who wants to work and who does my job every day, the same as I always did.
"I know that people know how good I am - most of the people that understand football know that they are wrong."
