Manchester United scout Hammer

Manchester United have stepped up their interest in West Ham youngster Domingos Quina, with scouts watching the 17-year-old score for Portugal under-19s against Spain this week, sources have told ESPN.

Quina joined West Ham last year after spending three years with Chelsea’s academy.

Manchester United, Arsenal and Paris Saint-Germain all previously considered a move for Quina before he signed for West Ham, but with the midfielder yet to commit to a long-term future to West Ham the Red Devils have stepped up their scouting of him.

Quina’s current deal doesn’t expire 2019 but West Ham are keen to tie him down to a long-term deal.

He has made two senior appearances for West Ham this season, both as a late substitute in Carabao Cup ties and spent 19 times on the bench last season. In the Summer he was linked to a  move to PSG and was on the verge of joining Sheffield United on loan until a deal collapsed.
