Things can change very quickly in football, as Tyrell Robinson can testify.
Early last month the 17-year-old was left frustrated after he was introduced as a substitute with just moments remaining of the UEFA Youth League game at home to Anderlecht.
In the past 24 hours, however, he has experienced two significant moments in his young career. Firstly a series of injuries to others meant that he made his debut for the U21s against Brighton & Hove Albion last night then, this morning, with Kieran Gibbs still out, Robinson trained with the Arsenal first-team squad at London Colney.
Circumstance may have dictated his inclusion but the Hale End product certainly merited the reward, too, after he delivered an excellent performance against Brighton, despite being asked to play as a left-back rather than in his usual left-wing position.
Robinson had given supporters a glimpse of his potential with an encouraging cameo in the Youth League fixture against Borussia Dortmund last week and he showcased his best assets again last night, rampaging forward and providing an important pass to set up one of Chuba Akpom’s goals.
A player who impressed for the U18s last season whilst still a schoolboy, Robinson is an intriguing talent, but he has had to be patient for opportunities so far this season and has started just five times for the U18s in 2014/15, partly owing to a spell out through injury.
Capable of operating on the right flank but more at home on the left, Robinson featured at left-back for the U21s last night with Brandon Ormonde-Ottewill, Marc Bola and Tafari Moore all missing through injury. His trademark enthusiasm shone through and it seems likely that, even when those players return to fitness, Robinson will be eased into becoming a more regular member of the U21 squad as the campaign progresses.
