West Ham United striker Diafra Sakho reportedly had a falling out with manager David Moyes prior to his side's EFL Cup defeat to Arsenal on Tuesday night.
The 27-year-old, who was desperate to leave the Hammers during the summer transfer window, is said to have confronted Moyes regarding a £50,000 bonus.
Sakho was left on the bench as a result of the row, according to the Daily Mail, and was introduced with 25 minutes to play in North London.
Used 14 times as a sub in the Premier League this season, the Senegal international decided to ask Moyes about his lack of playing time when arriving at the Emirates Stadium - a match he was expected to start.
The same report suggests that Sakho feels victimised due to a lucrative bonus clause in the new contract he signed during the summer, which is triggered once he starts a league game.
