Former Manchester United fullback Arthur Albiston is convinced the Da Silva twins will prove their quality at Old Trafford.

Both Rafael and Fabio have come in for criticism in the past season.

But Albiston told manutd.com: "Rafael is so lively and bouncy - he's like a cat on a hot tin roof. He's just so springy. He's got to learn things as he definitely got caught out in a couple of games, notably the Everton draw when it was highlighted. But he's still learning and is only a young lad. It's all happening quickly for him in the time he's been here and he'll benefit from any disappointments.

"The manager and staff have got to look all the time for emerging, young players and Fabio is going out on loan so he'll benefit from that. He needs to play 20-30 games to get some experience.

"He's got to grow up and he should be fine. His brother has played more games and is used to everybody now so he should be fine with them being apart as it makes you grow up."
