The club is well known for recruiting players based on experience and records. This is a team who still field players who are aged 30 plus so its no surprise to me if they want to sign Di maria at age 34. They believe experience gets the job done so I don't think Juventus wanting to sign Di maria at this current stage of his carrer are worried about getting top performance from him.
Juventus have no plans for the long term. Their goal is to perform well next season. Because their performance last season was completely unstable. And so they want to take Di Maria to the team. Di Maria is a very talented player. Although he is older, but his fitness is good. It looks like he will be able to serve the team well for the next few seasons.
Juventus currently does not have a new player to land in Turin and the latest news says that only di Maria wants to be brought in from PSG but the transfer process has not been realized.because Juventus must immediately improve next season considering their poor performance in European competitions and also domestic last season where they could only finish in 4th place even though we knew beforehand that they were serious challengers in the race for the Scudetto title.but they stumbled last season
