Pep Guardiola's Manchester City chose to pay almost £65 Million for only 23-year-old Ruben Dias in the summer's transfer window and Pep Guardiola has no doubt that Manchester City have made a good purchase.

Ruben Dias has this season formed a strong duo with Englishman John Stones in Manchester City's central defense, Dias has played 13 out of 15 possible matches in the Premier League. the Portuguese defender has been having a good performance and he has so far conceded 13 goals, which is the least of all in the Premier League.

It is not inevitable to look at Dias' style of play that he is only 23 years old, and the Portuguese's age means that Dias can play an important role in the blue part of Manchester for many years to come.

If Diaz continues to enjoy the team he can even play more than 12 years added to his age.
