Mapou Yanga-Mbiwa has joined AS Roma on a season-long loan, with a view to a permanent move. The French defender had fallen out of favour at St James’ Park and was keen to move and the Italian giants came calling on deadline day. In truth, Yanga-Mbiwa’s Newcastle career never really took off after his £6.7m move from Montpellier in 2013. Initially bought by the Magpies when they thought Fabricio Coloccini was leaving the club to return to Argentina, the captain’s decision to stay provided Newcastle with a problem. Yanga-Mbiwa and Coloccini were never able to form a successful defensive partnership and the Frenchman was soon replaced by the more dependable Mike Williamson. Yanga-Mbiwa made most of his 37 Premier League appearances at right-back but was never good enough there to displace Mathieu Debuchy or new signing Daryl Janmaat. The 25-year-old’s lack of physical presence and total inability to head the ball soon frustrated Alan Pardew to the point where he was actively looking to sell the player and Roma have provided the former Montpellier captain with an escape route. There is little doubt that Yanga-Mbiwa can go on to re-establish himself as a good player in Italy but the Premier League never suited him and his departure will not anger too many Newcastle fans.
