When footballers retire, it can be very easy for them to put on weight.

After all, they’ve spent their whole lives carefully watching what they consume and training almost every day. Who can blame them for letting go a bit when they finally hang up their boots?

But some retired professionals, to their credit, try to ensure they stay in shape when they’ve stopped playing and replace their daily training sessions with daily gym sessions.

One man that has certainly done that is Rio Ferdinand.

The former Manchester United defender is probably in better shape now than he ever was during his playing days - as seen in numerous images and videos he posts on social media.

But while we’re praising him for his incredible physique since retirement, not everyone is willing to let him get away with his constant workout uploads on Instagram.

Step forward, Cristiano Ronaldo and Patrice Evra.

The two former United defenders have left numerous comments on Ferdinand’s images and videos in the past and have done so once again.

Ferdinand posted a rather bizarre video of his latest exercise which shows him doing ‘bear crawls’ with dumbbells. In truth, it looks strange and Ronaldo and Evra were always going to troll him.

Ronaldo was the first to comment with the Portuguese superstar asking: “Wtf again is that ???????”

Ferdinand replied with: “I told you before it will mess you up bro! Start now and you might play until you are 50!!!”

But Evra soon joined the conversation - and Ferdinand trolling - with: “First man ever walked?? Can you please stop @rioferdy5 or you can come and wash my floor bro I love this game ahhaahahahahahah”.

All three former United players are all in very different roles following their departure from Old Trafford.

Ferdinand is a regular pundit on BT Sport - oh, and a full-time gym freak.

Evra moved from Juventus to Marseille in January - despite being linked with a return to United.

Meanwhile, Ronaldo is the Ballon d’Or winner and is looking to lead Real Madrid to La Liga and Champions League glory this season.

Despite them them moving on from the Red Devils, it seems Evra and Ronaldo still have plenty of time to poke fun at Ferdinand and his Instagram posts.

But Ferdinand probably has the last laugh because, judging by his recent pictures, he’s probably got a better physique than both of them right now.
