United States defender Matt Miazga has been recalled by Chelsea from his unsuccessful loan spell at French club Nantes and loaned to relegation-threatened English Championship side Reading for the rest of the season.
Chelsea acquired Miazga from Major League Soccer's New York Red Bulls in January 2016, but he made just two appearances during the remainder of that season and was loaned to Vitesse in the Netherlands for the remainder of 2016-17 and last season.
Ole Gunnar Solskjaer made it five wins from five as caretaker boss at Manchester United as they laboured to victory over Reading in the FA Cup third round.
Juan Mata's penalty, awarded by VAR, gave United the lead midway through the first half before Romelu Lukaku's neat finish doubled the lead before the break.
Reading, second bottom in the Championship and without a win in 11, battled well and troubled a flat-looking United at times and fashioned numerous chances that should have been put away.
