The Liverpool legend has already been back and forth on the social media site with the Foxes man this season.
Back in March, Simpson had a go at Carragher for wearing an Everton training kit while doing some filming with the Goodison Park team for Sky Sports.
Carragher and Simpson then engaged in a lengthy Twitter exchange – which was pretty funny to be honest.
And the former Reds defender obviously hasn’t forgotten about it, taking to Twitter today to reignite the feud with a hilarious tweet about the Leicester right back:

The tweet has been retweeted over 11,000 times and liked almost 25,000 times – so everyone is aware of the Carragher/Simpson feud.
And we’re looking forward to what Simpson will respond with.
As for Carragher and the snake, we’ve no idea what that picture is all about. But, then again, who cares?
