Ole Gunnar Solskjaer is reportedly keeping tabs on Rostov's Norwegian midfielder Mathias Normann.
The under-pressure Manchester United boss has previously managed Normann at Molde, having signed him on loan from Brighton & Hove Albion.
The midfielder, now at Russian outfit Rostov, has had a fine start to the campaign, winning the Player of the Month award for September in the Russian Premier League and earning his first international cap for Norway.
Normann is a primarily defensive player but has chipped in with one goal and three assists in 11 league outings.
Rostov value their man at between £15m-£20m, with Tottenham Hotspur and Sevilla also thought to be interested.
