Manchester City fullback Kyle Walker admits Newcastle winger Allan Saint-Maximin gave him a huge test last week.
Walker said it was tough to compete with Saint-Maximin last week in City's 3-3 draw at St James Park.
"I probably gave Saint-Maximin too many actions at the start of the game which got his confidence up," the 32-year-old defender told the Manchester Evening News.
"[It was] probably one of the toughest [games] that I have had in a long time.
"It is all about the mind and these players play with confidence.
"It is down to us as full-backs to make sure their confidence is low, we can get on top of them and be a little bit aggressive."
