Jamie Carragher and Gary Neville are two of the best pundits around, and neither is shy when it comes to dishing out jibes on Twitter.
Neville was in the commentary box as his former club Manchester United were humiliated by Chelsea on Jose Mourinho's first return to Stamford Bridge with his new club, and Carragher could not resist a dig at his colleague post-match.
In fairness, the former Manchester United captain gave his ex-England teammate an open goal, posting a selfie of himself on a motorbike, simultaneously looking terrified and in the midst of a midlife crisis, in the wake of Mourinho's heaviest ever defeat in the Premier League.
Having seen his former club Liverpool pull six points clear of their fiercest rivals by beating West Brom on Saturday, Carragher was understandably in no mood to pull any punches.
As for Neville, maybe it would be an idea to lay off the selfies.
