I read PSG would bekeen to sign Matip. If we get a good sum of monye for him, I think we should sell him. He's too injury-prone. If we can get something like 35M, it's more than enough to get a decent CB to replace him.
Don't get me wrong, Matip is a very good CB but we cannot rely on him and if PSG wants to give us a big sum for him, I think we should take it.
