Cesc Fabregas wearing a Chelsea shirt is still an image which looks a little odd after nearly a full season, thanks to his extensive history with Arsenal.
The Gunners decided against re-signing him from Barcelona in the summer, and he shocked the world by joining the Blues instead.
Some Arsenal fans have adjusted better than others to the Spaniard's choice, but over the weekend one supporter showed he is still a little bitter about it.
He sent a message trolling supermarket giants Tesco and midfielder Fabregas, branding the former Gunners captain a 'rat'.

Fabregas may yet have the last laugh though.
He inspired Chelsea to a 2-0 win over Arsenal earlier in the season, assisting Diego Costa for the second, and is on course to win his first ever Premier League title.
Chelsea are six points clear at the top of the table and have a game in hand, but there is the considerable task ahead of a visit to The Emirates to face the in-form Gunners in late April to tackle first.
