Marshall: 'Ronaldinho...Obviously (Arjen) Robben is only about 3 or 4 years older than me, but he's one of my idols too. Obviously playing in the same position as me, I just love what he does.'

Marshall: 'When I was at Barnet, I played against Arsenal. It was only pre-season but it was still a great experience because they played all their first team. It was unbelievable playing against the likes of (Andrey) Arshavin, and I think (Robin) van Persie played in that game too, just to name a couple.'

Marshall: 'I'd say Michael O'Connor, Jonathan Douglas and Anthony McNamee. I learnt a lot from Anthony McNamee as well because he played in the Premier League and obviously had a sustained career. I've never seen someone who could cross a ball as good as he could and get out of tight spaces. He had asthma, so he couldn't really run for long distances, but once he squared his man up, he was unbelievable.'
