Speaking on his Fozcast podcast, Foster said: “Being a goalkeeper for United is the hardest goalkeeping position to play in world football. You need someone with broad shoulders.
“I’ve watched a lot of videos of him [Lammens] on YouTube…and he looks on the eye test like he’s a competent goalkeeper. I’m yet to see what he’s like with the ball at his feet though and I think he’s a panic buy.
"United have probably always got some sort of list of goalkeepers that they look at and they keep tabs on. There will be scouts all over the world…but I don’t think they’ve done an in-depth analysis. A deadline day goalkeeper signing tells me that your club is desperate.”
