Roman Pavlyuchenko has reportedly been involved in a training ground bust-up with Tottenham Hotspur assistant boss Kevin Bond.
The pair clashed over the Russian striker's lack of first-team opportunities, according to The Sun.
The paper also reports that the 30-year-old verbally attacked Harry Redknapp, even though the Spurs manager was absent from training.
Pavlyuchenko signed for Tottenham from Sporting Moscow in 2008 for £13.8m.
He has yet to start a Premier League game this season, and Lokomotiv Moscow are understood to be looking to submit an improved offer after having a £6.5m bid rejected.
Tottenham are currently third in the Premier League with 46 points from 22 games.
