Marco Materazzi feels the huge sum Barcelona paid to sign his former Inter team-mate Philippe Coutinho from Liverpool is a simple function of the transfer market.

BARCELONA, SPAIN – JANUARY 08: New Barcelona signing Philippe Coutinho is unveiled at Camp Nou on January 8, 2018 in Barcelona, Spain. The Brazilian player signed from Liverpool, has agreed a deal with the Catalan club until 2023 season. 

Barca parted with a fee that could reportedly rise to £142million to secure the services of the Brazil international.

Speaking to Omnisport about Coutinho, the former Italy international said: “I’ve been lucky enough to play alongside with him when he was just 15 years old and he was doing his first trial for Inter.

“I can tell you he [is a] huge player.

“Prices always depend [on] the offer and the request. If there’s a team asking that much and there’s another willing to pay that amount, it’s not Marco Materazzi’s problem.”

Materazzi also welcomed Inter’s signing of Lisandro Lopez, and backed the defender to make an impact.
