United loan Bolton defender
Manchester United's only signing of transfer deadline day was 21-year-old Andy Kellett from Bolton.
United have been linked with a number of the continent's top targets this window, including Mats Hummels, Kevin Strootman and Marquinhos.
But their only incoming on deadline day was that of little-known Kellett, who has only played four times for the Trotters.
The defender, who was on loan at League Two Plymouth until three weeks ago, moves to United on loan until the end of the season.
As part of the deal, which was announced just before midnight, 19-year-old United defender Saidy Janko has joined Bolton until the end of the season.
United's other signings of the window were free agent Victor Valdes and 20-year-old Libyan right-back Sadiq El Fitouri from Salford City.
