Sergio Romero has accepted that he is not guaranteed the number one position at Manchester United following David de Gea's failed move to Real Madrid.
Romero, who was playing with Italian side Sampdoria last season, was signed on a free transfer by United manager Louis Van Gaal and has started in all four of the Red Devils' league matches thus far.
De Gea, who was United's player of the year last term, saw his dream move to the Spanish giants fall through at the last minute and is now expected to reclaim his place in the side for United's match against rivals Liverpool on Saturday.
Romero told canchallena.com: "Playing for United is a dream and if God helps me this dream will never end.
"As I have been saying: I have to thank Van Gaal for trusting me. But let me tell you, I don't think that the goalkeeper spot in United is already mine.
"I do know that I have a huge support from Van Gaal and his staff.
"Although I had not done a pre-season, I started playing for the biggest club in the world."
