Solskjaer warns: ManU stars have to work their way back into his plans

"Good players can play well together... Scott, Nemanja, and Fred are also good players so there's competition for those places. I can see lots of different combinations in that midfield, different systems as well.

"I wasn't happy with the game against Palace, of course. We weren't ready to play at the intensity that we needed.

Chris Smalling, Sergio Romero, Marcos Rojo, Phil Jones, and Andreas Pereira have failed to play in either of United's games this season, including the Carabao Cup match against Luton.
