Ex-Newcastle midfielder Lee Clark is allegedly in talks over a move back to the club.
McClaren, 54, is to be appointed Newcastle boss later this week according to the BBC, having left Derby County last month having failed to break into the Championship play-offs.
The former England boss will be attempting to improve the Magpies' fortunes after this past season's relegation battle, with interim boss John Carver set to leave the club after a nightmare spell in charge of the club.
McClaren will therefore need to establish a backroom staff around him - and the Daily Mail believe that talks have already been held with Lee Clark over the role.
Clark, 42, spent two spells with Newcastle as a player, racking up over 200 appearances for the club before turning his hand to management with Huddersfield Town and Birmingham City.
Last month, the Wallsend-born manager resigned from his role as Blackpool manager, meaning he is now free to take the role of assisting McClaren if he so wishes.
The report states that discussions have already been held with Clark, though McClaren's former Derby assistant Paul Simpson is also believe to be in the running, with ex-Rams goalkeeping coach Eric Steele expected to make the move up to Tyneside too.
