Arsenal had Marquinhos to thank after they salvaged a 1-1 draw in a pre-season outing against Watford.
The Gunners are preparing for their Premier League season opener against Nottingham Forest in a matter of weeks and hosted the Championship side at their London Colney training base. It allowed Mikel Arteta to field a team mixed with senior players, fringe stars and academy hopefuls.
Marquinhos is very much still trying to prove himself at the Emirates having been sent out on loan to Norwich last term, but he scored the Gunners' equaliser ten minutes into the second half, with the contest finishing as a stalemate.
