Manchester United academy coaches are taking another look at Brazilian teenager Gabriel Martinelli.
The 16-year-old forward has returned to Carrington as part of an on-going trial from San Paulo-based side Ituano and played for a United youth XI against Lincoln City on Wednesday.
He replaced Nishan Burkhart after an hour at Sincil Bank as United won 2-0 thanks to goals from Brandon Williams and Millen Baars.
United have already bolstered their academy ranks this summer, with 16-year-old Belgian striker Largie Ramazani arriving from Charlton and French midfielder Aliou Badara Traore, also 16, joining from Sarcelles after spending time in Paris Saint-Germain's youth system.
Northern Ireland under-17 captain Ethan Galbraith has also moved to Old Trafford, while Spanish midfielder Arnau Puigmal is set to join from Espanyol.
Meanwhile, goalkeeper Theo Richardson, 18, has been handed a permanent deal after leaving Leeds United.
