Good news, Newcastle fans: For all the Magpies' activity in the transfer market over the past year, the club managed to pick up the bargain of the January transfer window.
The study found that Steve McClaren's side underpaid Swansea City to the tune of £11.5 million for Jonjo Shelvey, though it also concluded that Newcastle overspent £5.4 million on Tottenham Hotspur's £12 million winger Andros Townsend.
