Pietersen is a die-hard fan of Chelsea football club, while Yuvraj supports Manchester United.
Chelsea defeated Manchester United 3-1 on Sunday to seal a place in the final of the FA Cup. They were helped by two errors from goalkeeper David de Gea and an own goal by Harry Maguire.
While the Chelsea supporters celebrated the win, there was one of them, Kevin Pietersen who took the opportunity to give it back to Yuvraj Singh, a Manchester United fan.

Pietersen has often been taunted by Yuvraj on Twitter and the banter just took a turn for the former England cricketer with a thumping win by Chelsea.
Tagging Yuvraj in a tweet, Kevin asked Yuvraj if he is doing fine or not. "Hi, @YUVSTRONG12 - you ok mate?!" he asked and the ex-India cricketer replied: "Haha no mate I’m not I’m hurting."
Pietersen invited Yuvraj to watch the Champions League with him. It was a dig at Manchester United, who couldn't qualify for the Champions League this season.
"Just checking. Lots of talk a few weeks ago. Just checking you still wanted to chat?! Hope you recover well! You can come watch Champions League as my guest anytime," Pietersen wrote.
"Hmmm let’s see we never give up @ManUtd," Yuvraj responded.
