After starting two successive wins, Arsenal made it three draws on the bounce in their UEFA Youth League clash at home to Marseille.
The Gunners drew 1-1, but had to play the second half with 10 men after captain Isaac Hayden was sent off in the 44th minute.
After being brought down by Zinedine Machach, Hayden appeared to kick out at an opponent and was handed an instant red card.
The score was 1-1 at the time after Arsenal's Kristoffer Olsson scored a 35th minute penalty, cancelled out four minutes later by Antoine Kisaku - who scored a winner against the Gunners in the NextGen Series last season.
Machach himself was red carded eight minutes into the second half for a dangerous foul on goalscorer Kristoffer Olsson.
Despite their efforts, the young Gunners could not turn the tie, hosted at Borehamwood into a win. They top the group on nine points but Napoli could draw level by beating Dortmund tomorrow.
Arsenal's team lined up: Iliev, Moore, Ormonde-Ottewil, O'Connor, Plezeguelo, Hayden, Zelalem, Olsson, Toral, Kamara, Akpom.
Midfielder Zelalem was substituted at half-time, the teenager looking a little off the pace compared to his usual vibrant self.
Watching Arsenal fans were disappointed with Hayden's red card, making the following comments on Twitter about the team captain's lack of maturity...
Isaac Hayden is usually the captain but he really need an to cut out the immaturity in his game.— . (@DeanAFC1989) November 25, 2013
Isaac Hayden sent off, not really a fan of him tbh— Humza (@HumzaSheikhAFC) November 25, 2013
Hayden loves a red card. His challenge away at Colchester in pre-season was one of the worst tackles I've ever seen.— James Vella (@jvella7gooner) November 25, 2013
Hayden kicks out but misses player after reacting to a challenge and is sent off. Stupid decision. From ref and player.— gunnersopinion.com (@gunnersopinion) November 25, 2013
Hayden sent off for the U21s lol, reckless player.— DaG (@Wrighty_8) November 25, 2013
