Chelsea are refusing to deal with Tottenham over a potential loan deal for Michy Batshuayi, Sky Sports News understands.
Batshuayi's representatives are understood to have offered the player to Spurs following the collapse of a potential switch to Monaco earlier in the window - and the player is keen on joining Mauricio Pochettino's squad.
However, the west London club do not want to loan the Belgium striker to a direct rival for a top-four position, and there is a history of bad blood between the clubs regarding transfers.
In 2005, Frank Arnesen left his role as sporting director at White Hart Lane to move to Stamford Bridge, and then in 2013 Spurs were close to signing Willian only for Chelsea to usurp the deal at the last minute.
Chelsea have been looking for a new loan club for Batshuayi because his spell at Valencia this season has not worked out.
West Ham and Real Betis have agreed terms on a new Batshuayi loan deal until the summer with Chelsea but the cost of the player's wages are thought to be a stumbling block.
