What do Luis Suarez, Fernando Torres and Xabi Alonso all have in common?
Liverpool were unable to keep hold of them whenever other clubs expressed an interest in signing them.
And they will be desperately hoping that Philippe Coutinho isn’t added to that list in the upcoming transfer windows.
The Brazilian has been in fantastic form for club and country this season and has attracted interest from Real Madrid and Barcelona. But, with the Reds seemingly capable of maintaining a title challenge this campaign, there’s hope they can keep hold of the talented playmaker for the time being.
Coutinho is just two goals away from becoming the top-scoring Brazilian in Premier League history - but there are a couple of world-class players from his native country that never quite made it to England.
That includes Coutinho’s hero, Ronaldinho - who he describes as “definitely the best I've ever seen play”.
To be fair, Coutinho’s style isn’t too different from his idol.
Not especially quick but with incredible dribbling skills, both of them love to cut in from the left and let rip with their brilliant shooting.
But if Coutinho can have half the career that Ronaldinho had, he’d have done very well.
Ronaldinho played for Paris Saint-Germain, Barcelona and AC Milan, winning three league titles, a Champions League and a World Cup with Brazil - earning 97 appearances for his country.
At the age of 24, Coutinho is yet to win a league title but has already earned 23 caps for The Selecao.
But it seems the respect is mutual between the two players. Earlier this year, the former Barcelona star claimed that the Liverpool attacking midfielder would be perfect for the Camp Nou club.
Ronaldinho on Coutinho
“Coutinho has had a fantastic season - he has been one of the best midfield players in Europe - and when you think he has been playing in a team that has not been performing well that is an even bigger achievement,” Ronaldinho reportedly said.
“I can’t speak for him and I can’t speak for Barcelona - but I know what Barcelona look for in a player and he has all those qualities.”
Liverpool fans certainly won’t appreciate those comments but there’s no hiding from the fact that Coutinho would love to follow in the footsteps of Ronaldinho and succeed at Barcelona.
