Arsenal goalkeeper Emiliano Martinez believes the rigours of the Championship have prepared him for Champions League football.
The 22-year-old Argentine is set to make his European bow against Anderlecht in Wednesday’s Group D clash, with Wojciech Szczesny suspended after being sent off against Galatasaray, and backup David Ospina out injured.
Arriving from childhood club Independiente in 2010, Martinez has featured just twice for the Gunners since, with his last appearance coming in the chaotic 7-5 Capital One Cup win over Reading in October 2012.
The third-choice keeper played 15 times on loan at Championship side Sheffield Wednesday last season, however, and maintains that his stint in the second-tier has made him a much better shot-stopper.
‘I've been working on being more commanding in the box. I didn't have any experience before and I went to the Championship, which is all about crosses and making the right decision,’ he told the Daily Mirror.
‘I learnt a lot because I played nearly 20 games so I'm a completely different keeper now. I was working really hard and I played really well in quite a few wins and gained a lot of experience.
‘I've been working with Wojciech for nearly four years already. Since I came to Arsenal I've been working with him.’
Arsenal travel to Brussels sitting second in their group, following a 2-0 loss at Borussia Dortmund and 4-1 win over Galatasaray at the Emirates.
Anderlecht, meanwhile, go into the match joint-bottom, having drawn with the Turkish side 1-1 in their opening game in Istanbul, before suffering a 3-0 home defeat to Dortmund.
