Charlie Austin's future has been the subject of debate for months, but West Ham co-owner David Sullivan took talking too freely too far earlier this week.
Sullivan told the Knees Up Mother Brown Podcast that Austin suffered from dodgy knees and was not fit enough to be worth signing.
Austin reacted angrily, issuing a statement, as reported by The BBC, describing it as 'inaccurate, misleading and uninformed innuendo.'
The full statement via his Twitter page called Sullivan's comments an 'outrageous slur'.
Doubts remain over his QPR future, with The Mirror reporting earlier this month that Spurs are planning an offer. The Daily Star reported just earlier this week he is their plan B if a deal to sign West Brom's Saido Berahino cannot be agreed.
Tottenham and West Ham's rivalry has cranked up over recent years, heightened by the efforts of both clubs to build new stadiums.
The Guardian reported this summer the full story of how West Ham beat Tottenham to securing the rights to London's Olympic Stadium in which Spurs called for a judicial review.
None other than David Sullivan himself told the Sunday Times earlier this month he hopes West Ham can 'pick Tottenham off', and overtake them to become a top six club.
Austin can help dent that ambition by pulling Spurs further away if he signs, helping out not only what would be his new club - but proving his biggest public detractor wrong.
Indeed in a game of one-ups-man ship, such a deal might just appeal to Tottenham chairman Daniel Levy even more now.
