Garay would have no trouble at all adapting to the Premier League according to his club team mate Rodrigo.
The Argentina international has been scouted by Premier League Champions Manchester United and could join fellow South American Guillermo Varela as one of David Moyes' first signings at Old Trafford.
Speaking exclusively to Fox Sports Asia, Rodrigo described Garay as 'a very smart' footballer.
"Everyone knows he is a good, smart player - he was at Real Madrid. He may not have had much luck there but he has definitely proved himself in the last two years at Benfica.
"I do not know if he will stay because maybe he will go to England. I wish him the best as he is a very good person too."
Garay played only 25 league games in two seasons at Real Madrid before a move to Benfica, who were beaten in last month's Europa League final by Chelsea. Garay would be competing with the likes of Rio Ferdinand, Phil Jones, Chris Smalling and Nemanja Vidic for a place in United's defence.
Striker Rodrigo has also been linked with a move to the Premier League but ruled out a switch to Tottenham before the start of next season.
"I am staying at Benfica because they are the club that gave me the opportunity to play at a high level in the best competitions.
"We are in the Champions League next season and will have a good team - I want to stay and improve as a player and have a good season."
The 22-year-old, who was born in Brazil before moving to Spain as a teenager, is currently at the UEFA Under-21 Championship in Israel and enjoying playing alongside Barcelona's Thiago Alcantara.
"He is so so good and for me, the best in the world at our age.
"I hope he can go on to be as good as Iniesta or Xavi - he has the potential but anything can change in football in a matter of months."
