#17 Watford (£9.4 million)

That transfer fee looks like an absolute bargain for this man
The Hornets signed Abdoulaye Doucoure from Rennes in 2016, shelling out a club record £9.4 million. The central midfielder from France could not settle in quickly as he had a forgettable 2nd half of the season, scoring just once in 20 games.
This season though, the highly-rated midfielder has been in stunning form, having already netted 6 goals from midfield helping the Hornets achieve a great start to their current Premier League campaign. With his box to box abilities, the midfielder now looks like a complete steal.
#16 West Brom (£10.2 million)

Next on the list is another Englishman who holds the record for the highest transfer fee in January for West Brom. The Baggies spent £10.2 million on Jake Livermore to sign him from Hull City in 2017.
With West Brom having an abundance of average central midfielders in their squad already, spending a club record fee on another midfielder seemed a bit puzzling.
But surprisingly, Livermore has held his own at the Hawthorns becoming an all-action midfielder that Tottenham hoped they unearthed. A Spurs academy graduate, Livermore has gone on to play 7 times for England, with 6 of his appearances coming after moving to the Hawthorns.
