Well, not exactly.
The Brazilian was tricked into signing a Manchester United ‘contract’ following Chelsea’s narrow victory on Saturday evening, but we don’t think the document penned by Oscar is a legally binding one.
This stunt was performed by the chaps from CheekySport who had been canvassing fan opinion and, as the name suggests, getting involved in some mischief along the way.
Oscar, who started for Chelsea in this encounter with Manchester United, was on his way out of the stadium when he was approached for an autograph and, as ever, was more than happy to oblige.
Little did he know, however, that the piece of paper on which he scrawled his signature was actually a pledge to sign for Manchester United. Has anyone told Jose Mourinho yet?
Chelsea, meanwhile, moved themselves to the brink of the Premier League title as this win over Manchester United took them 10 points clear of second placed Arsenal.
But Manchester United felt aggrieved that it was not them to emerge from the fixture with maximum points, given that they had enjoyed a massive 70 percent of the ball during the tight contest.
Manchester United fans: what would you think if your club signed Oscar?
