Manchester United midfielder Nemanja Matic was full of praise for his new team as he described them "different" from the rest.
The Serbian was a surprise transfer this month as he left Chelsea to move to Stamford Bridge.
He says only two or three clubs can compete with Manchester United in terms of how big the club is, probably referring to Real Madrid, Barcelona and Bayern Munich.
"Everyone knows what Manchester United is about. It is different," he said.
"Chelsea is a big club, Benfica are the biggest club in Portugal. But Manchester United is Manchester United.
"Maybe you have two or three clubs similar to United, but it is one of the biggest clubs in the world for sure.
"When I came here for the first day, I could feel that the people at the club help you every day if you need something and supporters are very important for this club."
