Premier League footballers' performances are suffering due to worries related to gambling, according to a study reported in the Daily Telegraph.
The newspaper reports that Graeme Law, of the University of Chester, interviewed 34 current and former professional footballers, including international and Premier League players.
Law carried out the research as part of his PhD study, titled "Pay and conditions in professional football," and will present his conclusions at the British Sociological Association's annual conference in Birmingham on Thursday.
"Players were unable to function to the level expected, and this leads to resentment in the team about their gambling," Law said.
"Players gamble as a way of relieving the boredom on journeys to away games and after training on preseason tours. Contrary to popular opinion, their actions are heavily regulated and constrained, so they get easily bored.
"Previous gambling environments were more social and encouraged group interaction, whereas the internet now allows gambling to be done in private."
One Premier League player told Law: "I have lost a lot and I had a stinker because it's all I thought about during the game."
On Wednesday, Press Association Sport reported that Manchester City defender Martin Demichelis will not contest a Football Association charge over alleged betting offences.
Demichelis, 35, is accused of 12 breaches of FA rule E8 concerning matches played between Jan. 22 and 28 this year.
