Former Southampton youth coach Jason Dodd insists Alex Oxlade-Chamberlain will prove an Arsenal star.
Dodd, who coached Oxlade-Chamberlain during his time with the Saints, is confident the 21-year-old can fulfil his huge potential.
"He's pushed on since when he was at Southampton," Dodd told Sky Sports. "I remember when he was 15, he was only a very slight boy so we spoke to his dad [ex-England player Mark Chamberlain] and played him a year down so it was a case of understanding the player.
"We always knew with Alex that he was going to be special because he just needed to grow into his body. He was a good kid and we knew he was going to get stronger and stronger.
"Arsenal have got a bargain in my opinion because he will just get better and better.
"I feel for him this year because he's had these niggly injuries - hamstrings - that he's not really had before and it's really affected his performances this season because he hasn't been able to return to play as regularly as he would like to play."
