Manchester United goalkeeper Sergio Romero has explained the reasons behind his shirt number.

The Argentine wears No20 at United.

He told manutd.com: "With regard to colours, the club obviously makes the decisions on these things at the start of the season. Then you have to change, depending on what the other team are wearing; sometimes you wear black, other times green – and it's even been yellow at times. Decisions on when you need to change can come from the referee or the opposing team.

"The day I arrived in Manchester, there was a misunderstanding between myself and the manager, Louis van Gaal. He asked me what squad number I wanted, and I said 22. But he must have thought I'd said 21 because he told me if I wanted that number, I would have to go and speak with Ander Herrera. Anyway, it turned out Nick Powell had recently changed to 22, so I just said that no.20 would do fine. I had that same number during my first season with Sampdoria, so it was no problem at all for me."
