The 20-year-old insists they must be more clinical in the second leg

Arsenal right-back Hector Bellerin believes they still stand a chance of progressing in the Champions League despite their 2-0 defeat by Barcelona on Tuesday.

Bellerin, 20, bemoaned the opportunities his team failed convert as they were put to the sword by a brace from five-time Ballon d'Or winner Lionel Messi.

The Argentine put the Catalans firmly in control of the tie heading into the second leg at the Nou Camp in mid March.

Arsene Wenger has given his side just a 5% chance of turning things around.

The Londoners played well for a large portion of the game but Alex Oxlade-Chamberlain and Olivier Giroud were unable to make the most of their two clearest openings.

The misses would prove costly and Bellerin was quick to underline the importance of being clinical in games like these.

'We have had several chances to score first. It is hard against a team like this one and when you do not score, if they have chances, they can score. The first one was in a counter-attack and the second one in a penalty', he said.

'We have the heads up. We will face the second leg as we did with this first leg. We play good and we still have a chance. It is something very difficult, but we never give up.

'We have been a compact side but we were not as lucky as they were. We know we need to be more lethal.'

Whilst admitting it was a 'special' experience to face the club he started out at as a youngster, the defender insisted there was no room for sentiment, saying: 'I defend another shirt now and I am so proud of representing Arsenal.'
