Defiant King's Lynn joint boss Kevin Boon is refusing to give up on Town's FA Vase Wembley quest.

Boon is adamant the Linnets can overturn a three goal deficit in this weekend's semi-final, second leg tie against Coalville at The Walks.

'I'll guarantee you this is not over by a long way,' he said. 'The Walks is like a fortress and we are going to be that positive about it. We still believe we are going to Wembley and I won't take that away from the lads until 4.50pm this Saturday. I'm positive there is more left in this tie because at 3-0 down there was only one team trying to play football and we like to play football. We had a goal given offside and a blatant penalty that didn't go for us. In all fairness, we have given Coalville two goals with defensive errors but if you look at the negatives, deal with those and take them away, I think we can definitely do it.'

Boon admitted the high stakes semi-final cup clash in front of 1,800 fans at Owen Street may have affected a few of Town's younger element.

'Sometimes as a manager when you try to pick players up they actually come back stronger. There isn't much to do because they find something from within themselves,' he said. 'They know what they have to do now and I still feel the outcome this Saturday is that we will go to Wembley. You look at our form at home this year and we have beaten teams four and five and I think Coalville are beatable.

'I'm so positive. It was a big occasion and maybe it got to one or two. They are very, very young and that is why we've said moving forward it might take an experienced head or two to come and help us along but until that happens it's up to these players. They are a great set of lads and we're not pointing fingers at anyone. We just have to respond.'

Town's sluggish second half trait surfaced again in the Midlands.

'I don't know what it is but it seems like after the break we've been vulnerable to conceding all season long,' he said. 'If you just go back five minutes before half-time, Luke Thurlbourne went very close and if that goes in I believe we would have come out on top. Fair play to Coalville, they had a gameplan and tried to keep playing the long ball and turning us around – but this is definitely not finished. It's only half-time.

'I stood there about 10 minutes to go with us three down and still felt we can beat these at home.'

Town's management sprung a minor selection surprise with Charlie Defty retaining his place in defence after only his first senior outing of the season the previous week.

'We went with Charlie and Pat (Bexfield) down the right because we wanted to keep it solid,' said Boon. 'We watched them and they were strong down the flanks, although it turned out they picked up an injury in that area during the build up to this game. 'It's another game at our place. We'll just go out and play. There'll be 2,000, 2,500 people coming to watch and get behind us and we'll put on a show. We're unbeaten at The Walks and let's keep it that way.'
