Arsenal believe they have the 'new Rio Ferdinand' on their hands in young defender Zach Fagan.
Fagan told arsenal.com: "It's funny people say that because those are the two players that I like to watch all the time. I watch clips on Youtube and try watch games where they are playing. I like to focus on them, to see what they do on and off the ball, their positioning especially. I feel that I have learned from them but I am learning a lot in training too.
"Steve Bould was at the top of the game for years. I can relate and appreciate everything he says in training. You know when he is explaining things that he is giving the best advice and I do my best to take everything in and apply it."
Fagan is delighted with the arrival of Germany international Per Mertesacker.
"I was very pleased with the purchase of Per Mertesacker. I watched him closely at the last World Cup and he has a physical presence that we have perhaps been lacking. I am sure he will settle in and help us become more solid at the back."
