Carlisle United manager Greg Abbott has praised Nahki Wells for showing an “excellent attitude” during his trial and is convinced he can make his mark at the English League One club.Wells, 19, has agreed to join United until the end of the season after two short trial spells at Brunton Park. According to reports in the UK he is due to put pen-to-paper on his six-month deal on New Year's Day.Abbott's former Bradford team-mate Mark Ellis alerted the Cumbrians to Wells after working with him in the International Academic and Soccer Academy (IASA) in Leeds earlier this year.United had initially planned to bring the youngster back to the club for a longer trial but Abbott has since decided to hand Wells a permanent deal.Abbott said: “Nahki has spent a bit of time with us and has done well, but with the weather and his commitments with his studies we haven't quite been able to see him as much as we would have liked.“Having said that, he has shown us an excellent attitude and has demonstrated he has a bit of quality, so we've decided to bring him back so that we can take a much longer look at him.”“He definitely has quality, but the idea is that we'll get him here and see whether he can progress to become better than what we already have.“The challenge for him now is to come here, work with us full-time and show us what he can really do. The key is that people don't expect too much, too early.”Wells moved to England as part of the IASA, a programme where American youngsters can study for a degree and receive football training.He was recommended to the course by the Bermudan Football Association (BFA).He recently spoke of his dream of earning a professional deal in England.“I'm focused and preparing myself so when the door opens and I am offered something, I will be one hundred per cent ready,” Wells said.Carlisle are 12th in the League One table and are a game away from playing at Wembley in the Johnstone's Paint Trophy.Derek Broadley, the BFA technical director, has challenged Wells to make the most of his exciting opportunity at Carlisle.“I'm delighted for Nahki and I truly believe he has a good chance,” said Broadley. “He has a good skill base and from my short time working with him at Bermuda Hogges you could tell he has bundles of ability.”Broadley praised the IASA for successfully re-introducing former Ipswich trialist Wells into the professional game and believes more Bermuda players can benefit from the programme.“It's a second chance for Nahki. I thought the IASA was ideally suited to him and that's why I recommended him to Mark Ellis.“The programme is not suited to all of our boys and it's up to us to identify which players have both the ability and the right attitude,” Broadley said.“The great thing about this programme is that if things don't work out for Nahki he can return to the IASA and finish off his studies, which is an important safety net for him to fall back on.”
