"So I'm not quite sure why they're letting him go but they must have replacements lined up.

"United need a holding midfield player. Schneiderlien was let go, Schweinsteiger didn't get a game and so they need a replacement in there and Matic fits the bill.

"Michael Carrick can't play every single week so they need a player that can come in and do the same job as Carrick and Matic can do that."

The move reunites Matic with his former Chelsea manager Jose Mourinho, under whom he won a Premier League title in 2015.
