Manchester United have a history of spending big money on strikers with varying levels of success over the years.
Ruud van Nistelrooy was signed for £19m in the summer of 2001, a year after a knee injury had scuppered the Dutchman's move to Old Trafford. A tally of 150 goals in 219 games yielded a Premier League title, the FA Cup and League Cup in five years before he was sold to Real Madrid.
Fast forward to 2008 and United shelled out even more on Dimitar Berbatov to prise him away from Tottenham Hotspur. Daniel Levy's negotiating tactics were on full show with this transfer with it completed late on deadline day - it is something that United are wary of and have not forgotten when it comes to a certain Harry Kane this summer.
