Former Arsenal manager Arsene Wenger has revealed that his rivalry with Jose Mourinho originally began back in 2004 when Chelsea started spending money 'they didn't earn'.
The long-serving Gunners boss had several clashes with Mourinho during the Portuguese's spells with both Chelsea and Manchester United in the Premier League.
Both Wenger and Mourinho made barbs at one another in the press, while the duo also clashed on the touchline on numerous occasions ever since Mourinho originally joined the Blues.
The 72-year-old Frenchman, who is currently serving as FIFA's Chief of Global Football Development, has opened up on how the heated rivalry began when the 'Special One' originally arrived in England.
