Manchester City break the bank to sign Athletic Bilbao defender Aymeric Laporte

Manchester: Manchester City signed France Under-21 international Aymeric Laporte from Athletic Bilbao for a club-record fee of 65 million euros ($80 million) on Tuesday, taking its spending on center backs since 2014 to around $250 million.

The 23-year-old Laporte came close to joining City in the summer of 2016 - when Pep Guardiola took charge of the current English Premier League leader - but backed out of the move feeling he wasn't quite ready.

Eighteen months later, City clinched the signing of the left-footed, ball-playing defender after meeting his buy-out clause, strengthening the team's options in what has been a problem position for Guardiola and previous managers.

Laporte is the second most expensive defender in soccer history, with only Virgil van Dijk - who joined Liverpool from Southampton for 75 million pounds ($100 million) at the start of January - costing more.

Since City won its most recent Premier League title in 2014, Eliaquim Mangala has arrived from FC Porto for a reported 42 million pounds and Nicolas Otamendi joined from Valencia for 32 million pounds in 2015. Another center back, John Stones, cost an initial 47.5 million pounds in the summer of 2016.

City spent around 120 million pounds (then $155 million) on three fullbacks - Kyle Walker, Benjamin Mendy and Danilo - in the last transfer window.

Laporte made his debut in 2012 under former Bilbao coach Marcelo Bielsa - someone revered by Guardiola - and quickly became one of the Spanish league's most promising players. He said he likes to bring the ball out from the back, giving him the pedigree that suits Guardiola's vision and making him a likely rival for Stones to play alongside Otamendi.

"Defenders do this more than ever before," Laporte said in an interview with FourFourTwo magazine. "I spend as much time in training and matches working on starting attacks as I do stopping them.

"I'm usually quite calm in possession, so this helps initiate quicker, more fluid attacks from the back. I also like playing long, cross-field passes to change the position of an attack and give us another option. Variety is important."

Barcelona has previously been linked with Laporte, who has similar qualities to Gerard Pique - the Barca and Spain defender.

The size of the fee reflects the shortage of top-quality, left-footed center backs around at the moment - and comes two weeks after City turned down the chance to sign Alexis Sanchez because of the Chile forward's financial demands.

Laporte has signed a contract until 2023 and becomes City's most expensive player, with the fee exceeding the reported 55 million pounds spent on Kevin De Bruyne in August 2015.

City has four of the five costliest defenders in Premier League history - Laporte, Stones, Walker, and Mendy.

Laporte, who hasn't played for France's senior team, will be available for the knockout stage of the Champions League.

"All I know," he said, in an Instagram message to Athletic's fans on Monday, "is that I will never forget the place where I've become a better player and a better person. That's why this is not a 'goodbye,' only a 'see you soon,' and that I'll keep Athletic in my heart forever."
