The Sweden international was drafted in from Benfica for £31m earlier this summer.
After a shaky pre-season, Lindelof wasn’t named in Saturday’s squad to face West Ham.
Lescott, however, insists the 23-year-old ace will come good.
“I’m sure it will (take him a bit of time to settle),” Lescott told Sky Sports.
“They needed to add someone due to the injury situation last season and players not being as fit as Mourinho would like.
“He’s had an indifferent season, it’s been hard for him, obviously when you go to Man United the pressure is on straight away.
“Man Utd star Victor Lindelof didn’t feature against West Ham”
“The opponents they play in pre-season now aren’t the sort of team I played when I was growing up.
“There are a lot more established forwards, so it’s been tough.
“I’m sure given an opportunity he will show he is worthy of his Man United place.”
Following their 4-0 win over the Hammers, United will face Swansea at the Liberty Stadium on Saturday.
