Manchester United want a replacement through the doors before Diogo Dalot leaves for Roma.

Former United boss Jose Mourinho wants to bring Portuguese compatriot Dalot to the Stadio Olimpico during the January transfer window.

United are long-term admirers of Kieran Tripper, with the England international's club Atletico Madrid open to selling the right-sided defender who has just over 18 months left on his deal.

The Manchester Evening News says only Trippier's arrival to Old Trafford would allow United to let go of Dalot, who is currently the understudy to first-choice right-back Aaron Wan-Bissaka.

Dalot is yet to start a Premier League game in Ole Gunnar Solskjaer's squad this season, with the Portuguese international limited to just three substitute appearances so far all term.
