Guardiola has spent 236 million euros on centre-backs at Man City

Manchester City's signing of Benfica defender Ruben Dias has taken their spending on centre-backs since Pep Guardiola joined the club to 235.6 million euros. 

City have agreed a deal with the Portuguese club worth 68 million to sign Dias, who becomes their second defensive signing of the summer. Nicolás Otamendi will move in the other direction for 15 million. 

Despite investing heavily in defenders, City have failed to improve at the back under Guardiola, as Sunday's 5-2 defeat at home to Leicester City showed. 

In total, they have spent well over 200 million on centre-backs since Guardiola came in. Dias is the latest and the second this summer after City spent 45.3 million to land the Dutch international from Bournemouth. 

Those two will compete for positions in the middle of the back four this season with two more expensive signings from years gone by: John Stones (signed in 2016 for 55.6 million) and Aymeric Laporte (signed in 2018 for 65 million). 

Eric Garcia also remains at the club but his future is unknown. With a year to run on his contract, Barça are keen to sign him. City signed him in 2017 for 1.7 million euros in compensation. 

City have spent big elsewhere in defence, too. Almost 200 million has gone on full-backs in the Pep era: Joao Cancelo (65 million), Kyle Walker (52.7 million) and Benjamin Mendy (57.5 million), in addition to youngsters like Oleksander Zinchenko (2 million) and Philippe Sandler (2.5 million). 

In total, the investment on defenders under Guardiola is 415.3 million.
