Cape Town - Former England cricketer Kevin Pietersen had a fantastic Sunday - at the expense of Manchester United and their new coach, Jose Mourinho!
Pietersen, obviously a Chelsea fan, was watching as the Blues thrashed United 4-0 at Stamford Bridge in the English Premier League.
Pietersen was particularly critical of United midfielder Marouane Fellaini, who was taken off at half-time after not having the greatest of matches.
The match saw Mourinho return to Stamford Bridge for the first time since being named as Manchester United manager.
In Pietersen's defence, he was not the only one having a go at Mourinho and United on what was a tough day for the Red Devils.
Social media was alive with memes and jibes throughout the 90 minutes after Chelsea had taken a 1-0 lead inside 30 seconds.
Here are some of KP's tweets:
Is there a raffle every week in Manchester that Fellaini wins which gets him automatic selection for Man Utd?— KP (@KP24) October 23, 2016
Costa & Hazard could beat Utd by themselves today. Coincidental that they were 2 v unhappy players under The Special One...?— KP (@KP24) October 23, 2016
