Manchester United's capture of Sergio Romero will cover the potential exit of David de Gea, with Louis van Gaal still unsure where his first-choice goalkeeper's future lies.
De Gea has been constantly linked with a move to Real Madrid in the wake of Iker Casillas' departure from the Santiago Bernabeu, having blossomed into one of the Premier League's top shot-stoppers.
And with Victor Valdes set to leave the club over his apparent refusal to play in Under-21 matches last term, Van Gaal concedes Romero could be thrown in at the deep end if De Gea does leave United.
Van Gaal told MUTV: "I know him very well and I think in our situation, if De Gea is going or not going, it is always a threat and we have to take care, make sure that we are prepared.
"That is why I think it is very good that Sergio Romero is now a Manchester United player."
"He was also a former player of mine," Van Gaal added. "I was trainer-coach, manager of AZ Alkmaar in the Netherlands, I picked him up when he was 19 and he was a great talent.
"We became champions with him, with a minor club, and in the Netherlands it was a fantastic result of course."
