(CNN)Chelsea set a British transfer record with the signing of Argentina's World Cup winner Enzo Fernández from Benfica for £107 million ($132 million), the Portuguese club announced on Tuesday.
Fernández's fee eclipses the reported £100 million ($123 million) Manchester City paid for Jack Grealish and concludes a high-spending transfer window for Chelsea.
The London club -- currently 10th in the Premier League and in the middle of a disappointing run of results -- has spent liberally under the new ownership group led by American investor Todd Boehly, notably acquiring Mykhailo Mudryk from Shakhtar Donetsk in a deal worth $110 million in total.
Fernández becomes Chelsea's eighth signing of the transfer window after Benoit Badiashile, David Fofana, João Félix (on loan from Atlético Madrid), Noni Madueke, Mudryk, Andrey Santos and Malo Gusto, who will join in the summer after completing a loan spell at French side Lyon.
