Newcastle United reportedly want to sign Borussia Dortmund left-back Raphael Guerreiro as a free agent in the summer.

The Lowdown: Out of contract

Guerreiro is out of contract at Dortmund this summer, meaning that he can leave as a free agent at the end of the season.

The 29-year-old would certainly not be short of suitors, having amassed an impressive four goals and nine assists in 26 games in total over all competitions so far this term, mainly from the left-back position (Transfermarkt).

The Latest: Newcastle interest

Co-writing in his latest piece for 90min, transfer expert Graeme Bailey says that Guerreiro is 'wanted' by Newcastle, among a whole host of other clubs, as a free agent this summer.

Teams from both Italy and Spain, as well as some of Dortmund's rivals in Germany, have also made their interest known, while Leeds United, Aston Villa and Wolves are also all believed to be interested in his signature.

Burnley, who are currently in the Championship at the moment but look set to make a swift return to the Premier League under Vincent Kompany, are also thought to be thinking about making an 'audacious' attempt to try and sign Guerreiro, while the Magpies have also looked at Arsenal and Scotland left-back Kieran Tierney as a potential alternative.

The Verdict: Statement signing

Guerreiro would certainly be a statement signing from the St. James' Park outfit, as he has the potential to completely transform their backline for the next campaign.

Boasting a total of 214 appearances for Dortmund over all competitions, where he has notched up an impressive 38 goals and 45 assists from defence (four goals and 13 assists in 61 senior caps, including three goal contributions at the most recent FIFA World Cup in Qatar.

Hailed as an 'amazing player' by his manager at Dortmund Edin Terzic, and someone who 'oozes class' by journalist Josh Bunting, Guerreiro would be sure to make the left-back spot his own should he make the move to the Magpies, with Dan Burn, who has Eddie Howe so far this campaign, primarily a central defender by trade.

Guerreiro actually shares the same agent as the Magpies boss, and if the North East club could snap him up on a free transfer this summer it could turn out to be a real bargain in the future.
