"I can understand why Arsene Wenger did not want to re-sign him," Adams told the Daily Express. .
"They've already got Aaron [Ramsey], Jack [Wilshere], Alex [Oxlade-Chamberlain] and Santi [Cazorla] and I could go on. They have a lot of those types of players..
"Maybe Wenger thought we didn't need that type of player. It saddened me because he was Arsenal captain and it's a shame he's not coming back."
