Sir Alex Ferguson raised doubts when he signed Van Persie from Arsenal due to his age and injury record but he went onto play a key role in winning the league title for a record 20th time.
Ibrahimovic has won the league title at every club he has played at but he is 34-year-old – two years older than Van Persie.
Robson was quoted by the Metro as saying: “I think back to Sir Alex’s last year when everybody talked about Robin van Persie’s age and his injuries when he joined, but he won us the title with his goals that season. Hopefully Zlatan can do the same.”
The Dutch striker first made a name for himself at Arsenal spending almost a decade at the club before joining rivals United.
Van Persie’s move did not go down well with Gooners but the Dutch star did go onto win the trophy that had eluded him for eight seasons prior to his transfer.
Van Persie won the league title with United during his three-seasons at the Red Devils before joining Fenerbahce on a three-year deal last summer.
The experienced striker provided three assists and found the back of the net 22 times in 48 appearances in all competitions for the Istanbul giants last season.
