Paul Lambert's wine rack will soon be overloaded if Oli Johnson continues to prove top of the class at the Yeovil finishing school.

The 23-year-old is on loan in the West Country until mid-April – a deal which Glovers manager Terry Skiverton says has cost him a couple of bottles of expensive wine.

But after a Johnson special against Tranmere at the weekend took his tally to three in his last six appearances for Yeovil, there could be more vintage stuff on its way to Carrow Road.

Lambert sent Johnson to Yeovil to continue his footballing education, and the striker – whose initial one-month stay was extended – says he's doing just that.

Johnson, sometimes used as a second striker behind Andy Williams, says his game is developing with every appearance: 'Goals are what it is all about for strikers,' he said. 'It was heavy on the legs against Tranmere and was not a pretty game of football, but sometimes you have got to dig in with these type of games.

'I am definitely learning a new discipline and side to my game. It is something that I have had to do as football is not always about the pretty side of things, getting the ball down and playing it. I do prefer that side of the game but this is part of my education, really. I am learning to drop deeper and help the midfield, which I need to do.

'It is nice to know that I can settle now and all I am thinking about is playing for Yeovil. I have no thoughts of going back to Norwich, so I can focus on playing, which is good.'

Johnson's match-winning goal at Tranmere was all about instinct: former Canaries keeper Tony Warner headed clear, a defender's first touch was loose, Johnson saw the opportunity and from 25 yards or more lobbed the stranded keeper.

'It was a massive win in terms of importance and was three points going into games with three promotion-chasing teams,' said Johnson, who joined Norwich from Stockport in January last year. 'It was not a bad finish either.

'I could have taken a touch and tried to play in another player but it was just instinct. I was not sure if it was going to bounce and go over the crossbar or if a defender was going to get back for it. I was not sure until it hit the back of the net.

'It is up there with the best. I have scored some decent goals but it is definitely up there and is definitely one of the most important I have scored as well.

'This is the first string of games I have had in a while so I think I am still finding my feet and match fitness. But I have scored a few goals now and I do not think it is a bad return.

'It was quite a difficult game to play in and the pitch was not the greatest, but those are the sorts of games you have got to put in a battle and I think we did that. Everyone played their part and dug in.

'We have got a couple of games in hand on others but there is still a long way to go. You have just got to keep picking up three points and we will go into Tuesday with confidence. We are all pleased and we have got these three big games coming up against the so-called bigger teams in the league, so it gives us confidence.'

• Johnson played the full 90 minutes as Yeovil lost 1-0 at home to title-chasing Brighton last night – with former Norwich target Elliott Bennett getting the only goal.
