Odion Ighalo's loan move to Manchester United was the 31st notable signing the club have made following their last Premier League title win in 2012-13.
Since Sir Alex Ferguson's retirement at the end of that campaign, four different permanent managers have spent close to £1bn on new players without adding another league crown to their record haul of 20.
The Scot's chosen successor David Moyes got the ball rolling with the recruitment of Juan Mata and Marouane Fellaini, Louis van Gaal stepped up the spending on the likes of Angel di Maria and Anthony Martial, Jose Mourinho topped the lot with the then world record-purchase of Paul Pogba, while current boss Ole Gunnar Solskjaer has recently overseen the big-money signings of Harry Maguire and Bruno Fernandes.
They are averaging over £30m per signing on transfer fee alone, with an FA Cup, League Cup and Europa League title to show for it.
Their finishing league positions since Ferguson left: seventh, fourth, fifth, sixth, second and sixth.
