Arsenal striker Yaya Sanogo took a swipe at Chelsea manager Jose Mourinho on Twitter ahead of the club's FA Cup final win over Hull City this weekend.
The Daily Star on Sunday reports how the 21-year-old Frenchman - introduced as a second half substitute at Wembley - taunted the Portuguese tactician for his failure to deliver a single trophy during his first season of a second spell in charge at Stamford Bridge.
Earlier this year, Mourinho caused a stir when describing Arsene Wenger as a "specialist in failure", but it's the Gunners boss who had the last laugh after guiding Arsenal to a dramatic 3-2 extra-time victory.
It was quite a gamble taken by the former Auxerre star in the build-up to the showpiece final though, and after Arsenal found themselves 2-0 down inside the opening 10 minutes he probably wished he'd never posted the message.
"Last tweet bfore history, who would have guess we wld be in this position 1 month ago ? So José how much trophy did you get this year ?" he tweeted.
Thankfully for Sanogo the Gunners hit back with goals from Santi Cazorla, Laurent Koscielny and Aaron Ramsey, ending the north London club's nine-year spell without a trophy.
Sanogo meanwhile, has been subjected to criticism from his own supporters after a modest start to his career at the Emirates Stadium. He's often looked out of his depth when deputising for countryman Olivier Giroud in attack. However, he will quickly build a cult following if he continues to poke fun at the Chelsea manager and Arsenal's other rivals in this way.
The Blues finished the 2013/14 campaign in third place in the Premier League table, behind winners Manchester City and runners-up Liverpool, but ahead of Arsenal who settled for fourth place, and with it secured qualification for the Champions League.
