Former ​Manchester United goalkeeper Mark Bosnich thinks that David de Gea should be the number one choice in goal for the Red Devils, despite the emergence of Dean Henderson.

De Gea has been United’s best player for the last four to six years but has made some serious errors in goal this season. Henderson, meanwhile, has been in astute form for​ Sheffield United, where he is on loan from United, which has caused a debate on whether Henderson should replace the Spain international.

Bosnich, however, believes that as good as Henderson is, De Gea should still be the number one for them since he has been a great goalkeeper over the years.

"Henderson has done absolutely fantastic and proven himself to be an excellent goalkeeper," Bosnich told Goal.

"The bottom line is though that De Gea has done brilliantly over a longer period of time, he has had ups and downs but every goalkeeper does, there's no doubt about that. When you are at a bigger club it is far more exacerbated.

"At this moment in time, I would stick with De Gea. Dean Henderson is too good for the bench and it is a waste for him so I would keep loaning him out. Things can change very quickly. De Gea has had ups and downs but over a long period of time, he has been excellent. Unless they get ridiculous money for him, then I would keep him on."
