Chelsea boss Graham Potter will sell Chelsea striker Pierre-Emerick Aubameyang in the summer, according to Paul Merson.

Aubameyang has scored three goals in 15 appearances for Chelsea and was subbed on only to be subbed off during the Premier League defeat to Manchester City last week.

Merson told Sky Sports: “I think Aubameyang will now be moved on. I think they will cut their ties with him.

“As soon as you are sub-subbing a 30-something player, I think that is probably the end. Maybe you can get away with it with a younger player, but in football it’s one of those unwritten rules. It’s a don’t-do.

“But Potter did it with him at 33 and, for me, I think he’s done. It’s an example of why recruitment is such a big problem for Chelsea.

“They have brought a couple of players in already and it looks like they are going to have a go in the transfer window. They have to. The top four looks very far away right now but there’s a long way to go.

“But if you do that January business and, all of a sudden, Potter goes a week or two later, then another manager will come in and say, ‘Well, I don’t like him, I didn’t want him.’

“That’s what’s happened with Aubameyang. Potter did not want him, but if he is now sacked and someone else comes in, they will go, ‘Well, I don’t want that centre-half or that centre-half.’

“Then it’s like you are going around in circles again. That’s why Potter has got to be given more time in my opinion.”
