Redmond received a taste of the first-team scene when he was 19th man for the visit of Everton in March - just a week after his 16th birthday - and joined in the warm-up.
He was an unused substitute for Blues' final home match of the campaign. Had he got on, he would have been the Premier League's youngest ever player, as well as the club's, beating Trevor Francis's record.
Westley said he knew plenty had been trying to spirit him away from Blues.
"It's nice to have a couple others have been chasing," he told the Birmingham Mail. "Jake Jervis made his debut this season and all of a sudden there was interest in this lad of 6ft 3in with lots of potential.
"I'm aware that clubs have phoned Nathan at home, and he hasn't responded. He hasn't had a representative coming to us talking about this club and that club.
"As an England under-16 international, people were always bound to look at him.
"He's been in the dressing room on match day, he's been involved on the bench and one of the other big pluses for everybody in the Academy has been Alex McLeish calling people like him and Eddy over for training with the first team.
"That's a credit to Alex, Roy Aitken and Andy Watson that they see the players we have coming through and it helps us, it shows there's a path there for the young boys."
