The young stopper currently turns out for Polonia Warsaw, but it seems he has been on trial with the Red Devils for a number of weeks.
As reported by Fakt in his homeland, Kucz has already been the centre of interest from teams based in Germany, England and Scotland, although United are the only ones that appear to have offered him a trial.
It is claimed that Rangers, Bayer Leverkusen, Liverpool, Fulham and Everton have also contacted the player’s father, although it is not confirmed whether anything came of this.
Kucz has been spotted playing for United’s Under-15 team in recent matches, and it is unlikely that he will make an impact upon the Red Devils' first-team for a few years, if he does end up signing a contract with them.
Fakt likens the story to that involving Arsenal stopper Wojciech Szczesny, who himself transferred to England as a teenager. Arriving in North London as a 16-year-old, it took Szczesny three further years before he eventually made his debut for the Gunners.
The report calls Kucz an ‘amazing talent’ and names him as the ‘new Szczesny’, and the high interest in him is likely to rush through any potential transfer. No club would want to miss out on the youngster, and, having already secured him on trial, it appears as if United have the advantage in the race for the highly-rated stopper’s signature.
