Manchester United chiefs have no concerns over Cristiano Ronaldo's age should they move for the Real Madrid star.

The Manchester Evening News says Zlatan Ibrahimovic has managed to persuade his club into possibly bringing him back to Old Trafford eight years after he made the switch to Spain.

The Red Devils board have been left staggered at the supreme fitness of the 35-year-old, who proved that age was only a number.

Before injury cut short his season, Ibrahimovic banged in 28 goals in 46 games, and United's executive vice-chairman Ed Woodward believes Ronaldo, 32, will perform even greater than the former Paris Saint-Germain star.

The Portuguese maestro possesses greater speed and agility over the super Swede, and consistently performs on the big stage – as well as already having a superior understanding of the Premier League.
