FORMER Manchester United defender Mikael Silvestre has warned the Red Devils against signing Frenkie de Jong this summer.
De Jong, 26, has been heavily linked with a move to Old Trafford ever since Erik ten Hag took over.
United tried in vain to sign him all summer in 2022, with the midfielder ultimately snubbing them even after a fee was agreed with Barcelona.
However, he is now finally open to a transfer, and several clubs are reportedly prepared to battle it out for his signature.
Man Utd are expected to re-enter the race to sign De Jong, but Silvestre has warned that signing him could hinder Kobbie Mainoo's development.

The ex-United star told Bettingexpert.com: "If a player like Frenkie de Jong is available, he should be considered. But again you look at Kobbie and we talked about Scott, and we have Casemiro here.
"Will De Jong be an upgrade? Of course. Ahead of Kobbie but if you want to continue developing Mainoo and give him the time, I don't think De Jong should come in."
He added: "If you qualify for the Champions League, then signing De Jong makes sense. You have to consider him for sure.
"He's a top player but putting him in a midfield where the manager likes to play with two defensive midfielders, if you play with three, it could be a different proposition.
"So the answer is yes, do consider him."
