The 2009/10 campaign was one of transition for young Frenchman Francis Coquelin.
The 19-year-old arrived at Arsenal as a midfielder in 2008 and continued in that role for 18 months before moving to right-back.
His first start for Arsène Wenger's side came in the Carling Cup victory over West Brom and he featured again against Liverpool in the same competition, both times playing in the centre of midfield.
In January he was handed an FA Cup debut away at Stoke City. But he didn't play in his familiar midfield role. He started at right-back.
He continued in that position for the Reserves until the end of the season and grew into the role despite a shaky start. Expect to see more of Francis Coquelin in the back four next season.

"It was a hard game for me, it was my start game [in the first team] since West Brom and I hadn't really played right back before. But it is good to be versatile because I can play right back and midfield now. Arsenal gave me a chance at right back and they think I can play in that position so I am learning it and I hope it will pay off."
In February's Reserve League victory away at Chelsea Coquelin showed his physical prowess with some well-timed tackles to keep the likes of Borini and Kakuta at bay. He also made an impression by carving out opportunities at the other end with surging runs forward from right back.
