In 2009, superstar footballer Cristiano Ronaldo left Manchester United for Real Madrid after scoring 84 goals from 196 appearances in the Red Devils' famous No 7 shirt during his six-year stay at Old Trafford.
He followed the successful footsteps of Manchester United legends such as George Best, Bryan Robson, David Beckham and Eric Cantona. But since he departed for Real Madrid, those following have only managed to score just 15 goals among them.
They are Michael Owen, Antonio Valencia, Angel Di Maria, Memphis Depay and current occupant Alexis Sanchez.
Ronaldo's immediate replacement, former Liverpool, Real Madrid and Newcastle forward Owen, scored five goals from 31 appearances.
He was then followed by Valencia, who was signed from Wigan as a right-winger replacement for Ronaldo in 2009 but switched from the No 25 shirt to No 7 for the 2012-13 season. He could only score one from 30 appearances.
Winger, Angel Di Maria scored just twice despite playing 27 times for Manchester United following a £59.7million switch from Real Madrid.
Di Maria was followed by another flop, Memphis Depay, who scored twice from 29 appearances during the 2015-16 season before leaving for Lyon.
Incumbent No 7 Alexis Sanchez, who earns a whopping £500,000 per week at Old Trafford, has so far been able to score just 3 goals from 32 appearances.
It's safe to write that no player has been able to replicate the success of the famous No 7 shirt since Cristiano Ronaldo left the club 10-years ago.
