The two clubs meet this weekend.
"There's been an improvement up there, no doubt about that," Bowen observed.
"They got a great result against City in their last game. It was a good goal to get in front and then there was a rearguard action to defend it, which is only natural.
"Wes Brown coming back into things after a long injury lay-off, and looking somewhere near his best already, has also helped them."
