Crystal Palace hero John Salako believes Aaron Wan-Bissaka could struggled to deal with the pressure at Manchester United.
The 21-year-old fullback is on the verge of completing a 50m switch to United.
And Salako has coached the Englishman before and believes his personality won't suit the bright lights of Old Trafford.
"When you go to United you're under scrutiny, you're in front of 75,000 people week in, week out," Salako told Love Sport.
"They want him to go forward and create like a Trent Alexander-Arnold, or the lads at Liverpool or Man City. He's a quiet lad and doesn't say much and that's another thing that concerns me about going to Old Trafford.
"He's going to be in a dressing room with fierce characters, big characters who want to win, the crowd and dealing with the press. But he seems a very private, quiet, insular lad."
