Martinez is not only good at defense, but since he joined Manchester United, he has shown in every match how vital he is in the central defence of Manchester United. Apart from that, he has been the only defender that has made a successful and perfect pair with Varane.
Lindelof and maguire in the other hand, do not have a perfect pair with Varane.
He deserves a contract extension with better incentive because of his team play and ability to control the ball in the defense . With him the Manchester United goalkeeper does not make many leg mistakes, even if he is, so poor in kicking the ball.
Since Martinez joined Manchester United, he has given a new color to the Mnachester United defense. He even succeeded in shifting defenders who are usually always the main players in the squad. The role of Martinez is very important to cut off every attack made by the opponent. Indeed, at the beginning he joined many who doubted him, because as a central defender, his posture was considered disproportionate compared to other defenders, but he was able to show that he could play well and provide comfort for Manchetser United's back line.
That depends on napoli whether the club is willing to sell him or not. As far as i know that if napoli only accepts the offer that will be surpassing the clause release. it has been clearly stated by the napoli president if he will always reject any transfer amount that will be less then what he has expected.
I know that if such amounts will not be possible to be bought by another club. Even some clubs like manchester united and chelsea won't even spending beyond 100 m anymore.
In the end this returns to business as well because even though they are still trying to arrest Osimhen but when there is a club that dares to pay according to the clause requested then there really is no reason for Napoli even though he is a good player but business is still number 1 .
My hope is actually that he will still stay because indeed that will still be very good for Osimhen but when he decides to move then he really has to see if the club he will stay at is suitable or not.
That way Napoli is ready to let go of players who are key to their game on the front lines, as long as the price offered matches what they want. This kind of thing is very common in football, because after all business is also important to make them profit from selling players. Now we are just waiting for which club can make the offer that Napoli wants.
At the moment the big clubs want Osimhen more than 2 clubs, and they come from various top leagues. So he can add to his experience for the future so that he is even more mature.
