Manchester United manager Ole Gunnar Solskjaer admits Dean Henderson is 'not the most patient' player.
Some have called for the 23-year-old to replace David De Gea in goals after the Spaniard's poor performance in the draw with Everton last weekend.
And Henderson could get his chance to impress in Tuesday's FA Cup fifth-round clash with West Ham United, having played just three times this season for United.
"Dean has done very well when he has got the chance and matured. He wants to play every game because he knows he'll perform well," said Solskjaer.
"Dean's developed his game and improved since he's come here.
"I know he's not played as many games as he would've done last season, but you see every game he plays and in training his improvement, working hard on aspects we've spoken about.
"I've been impressed with his attitude and work-rate. Of course he's, how to say… he's not the most patient guy."
