Marcus McGuane: Arsenal midfielder signs for Barcelona
Barcelona have signed Arsenal midfielder Marcus McGuane for an undisclosed fee.
The 18-year-old has made two appearances for Arsenal's first team in the Europa League this season.
Barcelona intend to play him in their B team and have set the buy-out clause in his three-year contract at 25m euros (£21.9m).
McGuane, who has played for England under-17s, U18s and U19s, joined Arsenal at under-6 level.
His contract was due to run out in the summer and he is reported to have turned down a new deal.
