Manchester United showed plenty of resolve but wasted a glut of chances in a goalless draw with Chelsea, while Arsenal went top of the Barclays Premier League on Monday.
United boss Louis van Gaal has come under increasing pressure in the last month following four consecutive defeats and a series of tepid performances, but the Red Devils showed glimpses of their best against the Blues at Old Trafford.
Juan Mata and Anthony Martial were both denied by the woodwork in a pulsating opening half, although at the other end Manchester United goalkeeper David de Gea produced a fine save to keep out a John Terry header.
Thibaut Courtois produced an outstanding reaction save from Ander Herrera's point-blank toe poke after the break, while Chelsea midfielder Nemanja Matic wasted a glorious opportunity when he blazed high over the crossbar when clean through.
Arsenal moved above Leicester for at least 24 hours after Mesut Ozil inspired the Gunners to a 2-0 victory over Bournemouth.
The German's corner was headed home by centre-back Gabriel in the 27th minute while Ozil himself finished a fine move just after the hour mark to help Arsene Wenger's side bounce back from their 4-0 mauling at Southampton on Boxing Day.
