James Chester has slammed Hull City loanee Hatem Ben Arfa, insisting that the French midfielder did not have the right attitude in their relegation fight.
Ben Arfa moved to the KC Stadium from Newcastle in August as Steve Bruce bolstered his squad, but the 28-year-old failed to score or register an assist in nine appearances for the club.
The Frenchman subsequently departed Hull in December as his season-long deal was cut short and Chester has now condemned Ben Arfa's attitude.
"I think maybe the most disappointing thing was Ben Arfa," he told reporters. "He showed an awful lot of ability in training, but you just wanted to bang your head against a wall.
"The ability he showed in training is the ability that only certain players have. He could turn a game on its head and get you a goal from nothing. That signing, you could see why the gaffer brought him here.
"I'm not sure his attitude was to the level of everyone else, so that was frustrating because he would have been the player that if you were struggling to get the goals, he could have got them against Burnley.
"He could have used a bit of magic and scored us a goal but again, you just wanted to bang your head against a wall.
"It's the least you expect, for someone to run around, and the most frustrating thing for us was that you could see the ability that he had.
"For him to not really want to use it to his full potential - he's better than many of our players here so, it was more frustration."
Hull lie in 18th place in the Premier League - two points behind Newcastle - with two games of the season remaining.
