Norwich City's Murphy twins have been tipped for big things by the man who saw them terrorise his team at the weekend.

King's Lynn Town boss Gary Setchell was full of praise for the flying wingers after they inspired the Canaries' Under-21s to a thrilling 6-3 Norfolk Senior Cup quarter-final victory over the Linnets on Saturday.

Jacob Murphy scored a stunning second-half hat-trick to put the gloss on City's triumph and Setchell admitted the pair were simply a cut above his non-league charges.

The Lynn boss said: 'The two boys showed real quality. They've got a lot of developing to do but they're at a great club in Norwich City so I think they'll go far.

'I dread to think how good the first-team players are if they're so young and miles off it so to speak. We've played against some decent opposition this year, ie Telford and Eastbourne, but them two were far better than anything I've seen at that level. Hats off to them, Norwich City have got a couple of good boys there.

'Norwich played some unbelievable football and scored some great goals but we scored some great ones as well. It was an end-to-end to game. We wanted to win the game and we were in it. I handicapped us a bit by taking four men and my top scorer (Steve Spriggs) out of the side. But Norwich City are a very good team and we went for broke at 3-1 down - which is why we conceded six.'

Josh and Jacob, 17, signed professional contracts with the Carrow Road club until the end of 2014/15 season on Friday having progressed through the club's Academy ranks on their way to picking up England youth caps.

City Under-21 boss Scott Marshall insists the pair will have a future in the game at the highest level - but only if they keep working hard and improving on their weaknesses.

He said: 'We're delighted they've got the contracts. It's a little pat on the back for them - to say they're doing well. But in football you don't rest on that. You say 'go on and get the next one as quick as you can' because they've not achieved anything yet in the game and we want them to go and fulfil the potential they've got.

'It's great to get a bit of recognition but now they need to chase their next contract and get in and amongst the first-team squad. We're trying to create Premier League players and we need to keep improving the little rough edges that are there and get the best out of them.'

Lynn took the lead through Danny Beaumont in the county cup last-eight tie before Oli Durojaiye equalised from the penalty spot. City went 3-1 up after the re-start, through Durojaiye and Jacob Murphy, before George Thomson's strike gave Lynn hope. However, Jamar Loza and Jacob Murphy again put City in control.

Thomson scored again before Jacob Murphy netted his third to seal his hat-trick, put City into the semis and end the goal-crazy second half.
