Chelsea owner Roman Abramovich is furious with Real Madrid for going after Antonio Rudiger and could now pull the plug on any potential deal to bring Eden Hazard back to Stamford Bridge, according to reports in Spain.
Rudiger, 28, is set to enter the final six months of his current Blues contract and does not appear close to penning an extension.
As a result, the Germany centre-back will be able to secure a free move abroad at the turn of the year - and he has already entered initial talks with Madrid.
