Arsenal's third-choice goalkeeper, Emiliano Martinez, has told IBTimes UK he is trying to take advantage of the injuries of both Wojciech Szczesny and David Ospina to convince manager Arsene Wenger he deserves a starting role in his line-up.

The Argentine keeper made his Premier League debut during the weekend defeat against Manchester United, replacing Szczesny due to an injury, while he had another starting opportunity in the Champions League 2-0 victory over Borussia Dortmund on Wednesday 26 November.

When asked after the game whether he expects to keep the number one role once Szczesny and summer signing Ospina return to action, he said: "In football you have to seize every opportunity you get," he said to IBTimes UK.

"We have not had luck with the injuries of Wojciech and David but I will prove the boss that I can play on this team [as a starter] whenever I have a chance."

Having made his Champions League debut during the 2-1 victory over Anderlecht earlier in the season, the 22-year-old goalkeeper proved his worth against the Bundesliga giants, making a crucial save to stop Henrikh Mkhitaryan before half-time to secure a clean sheet for the Gunners.

"I already played against Anderlecht but do it at home in front of my supporters it has been something incredible," the Argentine added.

Meanwhile, when asked how Arsenal have managed to put behind them their back-to-back Premier League defeats against Swansea and Manchester United, he said: "We've been more focused than in the last games.

"Against Swansea and Manchester United we were a little bit unfocused but against Dortmund, we were better and we reached our target, which was to seal the qualification for the knockout stages.

"We have played very well and we want to keep the run in the coming games."
