It could also mean that he wants a first team spot as the best goalie of the world cup. He might have perceived that if he goes to Manchester United, there must be some kind of competition between him and De Gea which could result to having him keep either in the local league or champions league.
MU is tired with de gea since this goalkeeper was always making so many blunders. Martinez could always become the main choice to replace de gea in manchester united. Manchester united gave the de gea a new contract caused by it's willing to use him as backup for the main keeper.
MU is still trying to search which good keeper that can be the main keeper for the club. I will not be surprised if martinez will be going to the MU rather than chelsea caused by he will get guaranteed spot as the main keeper in this case.
It's very hard to pick which club that will be good for martinez yet this player is full with so many problems.
I remind you that if chelsea may try to offer kepa to the napoli as a part of effort by the club to sign victor osimhen from napoli. That's why chelsea is also looking for a new goal keeper.
For Chelsea, he must have weighed that he won't be playing European competition. The he saw that he will be the king in Totenham.
Totenham never get a good achievement and what's good about it? Totenham is actually nothing and it's a mediocre club. Joining in totenham is a bit mistake.
Look at what achieved by kane in totenham. He got nothing.
You didn't even need play in the european league competition to rebuild your club. It's not a mandatory for the club.
