Polish teenager Tomasz Cywka has finally signed a three-year contract with Wigan.
Midfielder Cywka agreed to join the Latics in March following an impressive two-week trial, but was forced to return to his homeland to complete his education.
The 18-year-old jetted in yesterday to put pen to paper, but again has quickly had to fly back to compete in the European Under-19 Championships, continuing his prolific record at under-age level.
Cywka has over 80 caps to his name for the under-18s and under-19s, and recently became the second youngest player in Poland's history to be capped at under-21 level.
After securing Cywka's signature, Jewell said: 'Until a player actually signs the deal, anything can happen, so I am delighted Tomasz is a Wigan player at last.
'He has a real chance to make it in the game, I think he has all the attributes to become a very good player as he has a great touch, vision and pace.
'Now he needs to adapt to the English game and make all that potential come good.'
Cywka, who has been learning English for the last five years courtesy of his parents paying for private tuition, appreciates it may take time for him to make his mark - but he is determined to succeed.
After apparently spurning the advances of Bayern Munich, Cywka said: 'Paul Jewell and Wigan pushed harder than any other club to sign me.
'I am very grateful to them for giving me this chance and I really hope I can repay the faith they have shown in me
'This is a very ambitious club and how the team performed last year was fantastic.
'How quickly I can make it into the first-team squad we will see, but I have come to England to learn and improve as a player and I will always be trying my best, that I can promise. I want to be the best I can.'
