We have Sanchez that can play on the right if necessary, and he is also a far better player than Salah, so again I don't see where Salah gets into our team other than on the bench at best.
Lingard and Martial are far better players, and as said previously, Salah was made to look better than he is, by having Coutinho next to him, lets see how he does without him there, the signs in games against Swansea and West Brom so far do not look too good.
So I would not have him anywhere near our club, especially not when we already have superior players.

Lets see how the rest of the season pans out, to me his game relied a heck of a lot on Coutinho's, and without him there, I have a feeling we will see a decline in his numbers both goals and assists.
Martial and Lingard are both great players in their own right, and are showing that this season, no way would I drop either for Salah.
