Manchester United have completed the signing of teenage Czech goalkeeper Matej Kovar, subject to international clearance.

Kovar joins from the Czech First League’s FC Slovacko and is a youth international, having won two caps with the Czech Republic’s Under-19s.

The 17-year-old becomes United’s second signing of the January transfer window following the more high-profile capture of Alexis Sanchez from Arsenal.

Kovar has signed professional terms with United and will join up with Kieran McKenna’s Under-18s squad.

United’s academy, overseen by former midfielder Nicky Butt, has handed out full-time contracts to several youth prospects recently.

Young midfielder Aliou Traoré put pen to paper on professional terms earlier this month, as did 17-year-old Spain youth international Arnau Puigmal.

Angel Gomes, the club’s reigning Young Player of the Year, was tied down to a senior deal in December alongside Aidan Barlow, another highly-rated local talent.

United are not expected to announce any further arrivals or departures on deadline day, despite Roma’s late interest in full back Daley Blind.
