Michael Bradley felt Arsenal made a mistake in signing Kim Kallstrom in January instead of him, his father Bob Bradley told Slate.

During the January transfer window, Arsenal were looking to add a midfielder at the same time the 26-year-old Bradley was looking to leave Roma.

Bradley completed a transfer to Toronto FC of the MLS following Arsenal's decision.

"I think American players and coaches have to fight really hard for respect," Bob Bradley told Slate. "In January, Arsenal were looking to add a midfielder and they chose Kim Kallstrom.

"Kim Kallstrom's not a bad player, but I think Michael feels pretty strongly that he's better, and so Arsene Wenger must not feel that way, and [Arsenal chief executive] Ivan Gazidis must not feel that way.

"So sometimes, no matter what you do, you don't get the respect you think you deserve."

Arsenal is owned by American Stan Kroenke, but do not have any Americans on their squad.
