Marquinhos again starred for Arsenal U21s in yesterday's 3-2 win at West Ham United.

Marquinhos made his second start for Arsenal U21 coach Mehmet Ali's side after impressing against Manchester United and it was the Brazilian who would prove to be the matchwinner once more.

Arsenal didn't have things all our own way in the opening exchanges and the hosts took an early lead through Kamarai Swyer, the Hammers midfielder capitalising on a Zach Awe error to snatch the ball and finish beyond Tom Smith.

Arsenal found ourselves level almost instantly from the restart, Marquinhos finding space at the back post to head home after James Olayinka's chipped cross at the end of a marauding run.

Khayon Edwards almost put Arsenal ahead midway through the half, exchanging passes well with Miguel Azeez in midfield, before seeing his instinctive effort cleared off the line in miraculous fashion.

Marquinhos scored the second moments before the break, rising well in a crowded penalty area to find the top corner with a glancing header from Charles Sagoe Jr's lofted ball.

Ali's men didn't have to wait too long for another after the interval, Olayinka turning to finish with aplomb past after a defence-splitting pass from Matt Smith found the midfielder in space in the penalty area.

Mipo Odubeko reduced the deficit against the run of play midway through the second half, racing through one-on-one and firing low beyond Smith.
