Emre Can and Sean Longstaff are among the options being considered by Ole Gunnar Solskjaer as Manchester United deal with a midfield injury crisis, sources have told ESPN.
Solskjaer admitted after the 2-0 defeat to Arsenal on Wednesday that injuries to Scott McTominay and Paul Pogba would "play on our decision-making" during the January window.
McTominay is expected to be sidelined for two months with a knee ligament injury while Pogba needs surgery on an ankle problem and could be out for a month.
The United board will back Solskjaer with funds to bolster his squad, but only if long-term targets become available.
