The flying leftie has made a late impact this pre-season, running Lazio ragged last weekend earned him a ticket to Goodison and he will be hoping that his angled strike will book him a return to White Hart Lane on Saturday against Villa.
Confidence plays such a big part that the boss reasoned that Matty's delivery was 20 times improved after his goal.
"We've got something to work on with Matty. He played well against Lazio in the first half, not so good in the second.
"Here at times in the first half and second he showed what he could do and he took his goal excellently. It can give him a lot of confidence.
"He knows what he's got to do. We're working and working with him and chipping away at him. He's got to be a little bit more consistent with his crossing. He gets in there at times and his crossing after he scored was 20 times better than before he scored.
"It's a matter of confidence and working at him to give him that belief. He'w willing to learn and look at things to try and improve as a player.
"That's what you want from a youngster."
Glenn says that Matthew Etherington can only improve with the confidence gained by his superb strike against Everton.
