Since being axed from the England job in 2008, the former Manchester United assistant has taken a variety of jobs in various countries, and he has been at several teams where players have shone, with those same players now being somewhat available.
Below is a list of five players McClaren may considering bringing back under his management:
Will Hughes (Derby) - Arguably the most sought after player in the Championship, Hughes has now been regularly playing first team football at Pride Park for three seasons. At 20-years-old, there is no rush for him to get to the Premier League, but if McClaren wanted to claim the crown jewel of his old club, he would head to Derby with an offer they couldn't refuse, and he'd be getting a classy playmaker with an eye for a pass if that bid was successful.
Tom Ince (Hull) - The young winger flourished under McClaren at Derby in his loan spell last season, and will be desperate to make an impact in the Premier League after once again proving that he is too good for the Championship. He'll have to leave Hull if he wants that to happen, with the Tigers getting relegated on the last day of the season as Newcastle claimed survival.
Bryan Ruiz (Fulham) - An undoubtedly talented player who impressed in the World Cup last summer, Ruiz shone at Twente under McClaren and many other managers, and would be a good signing to boost Newcastle's struggling creative and goalscoring departments, especially if they secured him on loan from Fulham.
Leory Fer (QPR) - Signing this powerhouse, who McClaren managed during his second spell in the Eredivisie, may come with its own warning - the midfielder has spent two seasons in the Premier League with two different clubs since arriving from the Netherlands, both have resulted in relegation. The 25-year-old is a Dutch international though, and would ensure the Magpies have one of the meatiest central midfields in the Premier League.
Douglas (Dynamo Moscow) - Defence is an area where McClaren will be having a real hard think, and he may come up with the unoriginal idea of bringing Brazilian centre-back Douglas to the North-East. The powerful 27-year-old has been linked to the club several times before, but he worked with McClaren at Twente before moving to Russia, something that may make a deal that little more likely this time.
