A Portuguese youngster signed for just £7.4million, there were hopes their club had unearthed the next Cristiano Ronaldo.
The reality could not be more different and after several terrible performances in a United shirt he was consigned to a life on loan before heading back to Portugal.
Loan spells Besiktas, Rio Ave and Pacos de Ferreira was followed by a permanent move to Benfica.
But he found a home in Spain, first with Eibar and later with Rayo Vallecano.
And he scored a screamer for the LaLiga club in their Cope del Rey semi-final with Real Betis.
As time was expiring and his side needing a goal, Bebe lashed in a 35-yard free-kick to give his side a lifeline.
It was a goal even Ronaldo himself would be proud of and maybe left United fans wondering why they did not see that quality for him during his time at Old Trafford.
But a 92nd minute goal from Borja Iglesias sent Betis through to the final of the competition.
