People who repeatedly type KDB,salah, Lukaku can you also type in the young and petulent players he sold who did not amount to much?
The above three were sold when they wanted to leave not when Mourinho asked them to. It was always chelsea's policy at that time to hoard in young good players and then sell them . They also sold matic and re-bought him again. Same with David Luiz. Lukaku and Kdb have already said they went because they wanted to go and not because Mou asked them to be sold, they were not patient enough and if that is the case and they made good careers then it happened to SAF with Pogba too, happened to juve with henry, etoo and madrid,Raul and athletico,Pirlo and Inter, pirlo and AC milan,etoo and barca, Robben and Real, bayern and kroos. It will happen again.
He has clearly improved Lingard and even rashford. Made smalling and jones looked like decent defenders and made even fellaini look useful at times.
Maybe martial becomes a world beater elsewhere, does it scare you? why should it? The simple truth is Martial wants to keep his interest ahead of the team, that is something that cannot happen as team is bigger than everyone. He isnt better than Lukaku as a striker, isnt better than sanchez on left, is worst at right wing. He should either bide his time and prove himself. He has 43 appearances this season at age of 22, which i think is a decent number for an inconsistent winger. He needs to play for Man utd and not for Martial FC. If he wants to change teams, he is welcome to, but he leaves on united's terms.
