3. Anthony Martial – £36m from Monaco, September 2015 – No one had heard of Martial when he signed for the Red Devils last summer but everyone knows who he is now. His fee could rise to over £50m if he achieves all of the things he is expected to and he will be Uniteds main focus of attack again this season. 7. Ander Herrera – £29m from Athletic Bilbao, July 2014 – Herrera is another transfer Moyes failed to get over the line before he joined under Louis van Gaal. The Spaniard is a fan favourite at Old Trafford but the jury is still out on him and whether he will make it as a Manchester United player. 10 10 1. Angel Di Maria – £59.7m from Real Madrid, August 2014 – Di Maria will probably go down as the most expensive flop in Premier League history, despite having three goals and ten assists to his name in his one season at Old Trafford. He never wanted to join the Red Devils and preferred a move to PSG, which he got a year later, for £44.1m. 10 8. Juan Sebastian Veron – £28.1m from Lazio, July 2001 – He’s a f****** great player. Yous are f******* idiots,” Ferguson screamed when criticism of the expensive Veron was mounting. He was a flop, though, and only spent two seasons at United before moving to Chelsea for £15m. 10 It now seems it is when, and not if, Paul Pogba rejoins Manchester United from Juventus.The Red Devils opened with a £86m bid and have reportedly upped it to £92m to try and test Juve’s resolve.However, the Italian champions are holding out for £100m up front for the Frenchman and it is believed United are willing to pay it.Manchester United are no strangers to paying big fees for players, especially since Sir Alex Ferguson’s departure from Old Trafford.When Pogba’s move is completed, he will become the club’s most expensive player by a distance, but who else has cost the Red Devils the big bucks?Click the arrow above, right, to see the ten most expensive signings Manchester United have ever made. 10 6. Rio Ferdinand – £29.3m from Leeds United, July 2002 – Ferdinand became the worlds most expensive defender and Britains most expensive player when he made the move from rivals Leeds to Manchester United. He is the most successful signing on the list, forming a formidable defence with Nemanja Vidic as United dominated both in the Premier League and in Europe. 10 2. Juan Mata – £37.1m from Chelsea, January 2014 – Another player loved by United fans but whose time could be coming to an end under Mourinho. Mata has scored goals and contributed plenty of assist but has not captured the imagination as he did at Chelsea. Moyes signed him in January 2014 in what seemed like a panic buy at the time. 4. Dimitar Berbatov – £30.75m, from Tottenham, September 2008 – Fergusons most expensive signing during his 27 years in the Old Trafford hotseat and a relative success. Berbatov won the Premier League golden boot in the 2010/11 season but will be most fondly remembered by United fans for his hat-trick against Liverpool at Old Trafford in a 3-2 victory in 2010. 9. Marouane Fellaini – £27.5m from Everton, September 2013 – Fellaini was David Moyes only signing in a disastrous first transfer window, and they overpaid for him as well. The shambles of that £27.5m move, which was completed at the last minute, should have been a foreshadowing for his time at Old Trafford. 10 10 10 10. Luke Shaw – £27m from Southampton, July 2014 (click the arrow, right, to see Manchester United’s most expensive signings) – When Pogba joins United he will be their most expensive signing by a distance, but who else has cost the club big bucks? Here, talkSPORT looks at the 10 costliest beginning with Shaw, who United made the most expensive teenager in the world when they signed him from Southampton in 2014. His first season was underwhelming and despite a bright start to his second, a broken leg in September kept him out for ten months. 10 5. Eric Bailly – £30m, from Villarreal, June 2016 – The former Villarreal man has now overtaken Ferdinand as the clubs most expensive defender after becoming Mourinhos first signing. At only 22, it will be interesting to see how he settles into the Premier League.
