Rafael's brother wasn't blessed with the best of luck in an injury-blighted debut season. But if fortune does favour Fabio in 2009/10, then it could mean double trouble for United's opposition...
Start to finish: Fabio's first-team debut came in the FA Cup fourth round clash against Tottenham Hotspur on 24 January. He impressed greatly but picked up a calf injury and limped off after 53 minutes. In truth, that was the tale of his first season at OT. Further first-team opportunities were limited, due to spells on the sidelines and Patrice Evra's excellent form. But Fabio consistently excelled at Reserve level, creating and scoring plenty of goals for Ole Gunnar Solskjaer's side.
In position: A right-footed, left-sided defender, Fabio is a definite goal threat - in March he netted a hat-trick in the Reserves' 4-1 Lancashire Senior Cup win over Rochdale - so he can also play further up the pitch.
Season highlight: Starting at Wembley in the FA Cup semi-final against Everton, with his twin brother Rafael on the opposite flank. He was eventually replaced by Evra but he can be proud of his display - not all teenagers get to play at Wembley in their first season!
Vital contribution: Fabio had a couple of run-outs in the FA Cup, helping United to reach the semis at Wembley.
