Paul Pogba is 32 years old. Arab clubs could have been a better option for him. I don't know how many more years he will play football. Although it varies greatly, on average, 34-35 years old is a good age to retire from football. He could have spent his retirement years earning a lot of money at Arab clubs. By staying in Europe, he has embarked on a new challenge. I think he wants to prove himself...
Yeah Pogba is also a Muslim, which mean he has no problem to play in Saudi Arabia.
Pogba will not able to prove anything, he played in mediocre team and even he get his performance back, he's already old and no top teams will interested to sign him. Imagine Pogba playing in Al Nassr, he will able to support Ronaldo to score many goals with his beautiful pass.
