Speaking on his YouTube channel, United icon Ferdinand said: "Just so you know, that voice note was from Thibaut Courtois. He let me know about Lammens because he’s a Belgian player, and he was just giving me the heads up as to what he’s like. He said he’s a huge talent, obviously not experienced yet but he thinks his style will be well-suited to the Premier League as well.
"So that’s a recommendation from probably one of the best three goalkeepers in the world, Thibaut Courtois, so I’ll take that. I keep seeing people talk about the talent and whatnot, but the problem is – can Man United afford to wait for talent to develop at this point in time? That’s the question."
