BARCELONA (REUTERS) - Barcelona's plans to sign Philippe Coutinho to fill the void left by the departure of Neymar appear to be back on after Liverpool released a statement on Friday announcing they will not sell the Brazilian playmaker at any cost, which was later followed by Coutinho handing in a transfer request according to several British media reports.

"We wish to offer clarity as regards our position on a possible transfer of Philippe Coutinho," said a statement from owners Fenway Sports Group on the Merseyside club's official website (www.liverpoolfc.com).

"The club's definitive stance is that no offers for Philippe will be considered and he will remain a member of Liverpool Football Club when the summer window closes."

It is the first time Liverpool's owners have commented on Barcelona's proposed bid for Coutinho, after coach Jurgen Klopp repeatedly insisted the Brazilian was not for sale.

"There is no price limit to let him go or a price that we are ready to give in," the German coach said on Thursday.

"Our goal is to have the best possible team. So we want to keep our guys and add new ones. That is our plan. Liverpool is not a club that has to sell players. That is set in stone. So what they pay in the end doesn't matter."

Hours after the strongly worded statement, Coutinho submitted a transfer request to leave Liverpool via e-mail, according to Sky Sports and the BBC.

It is understood that the club's stance has not changed in light of the transfer request.

Barcelona are looking to rebuild their squad after Neymar's move to Paris Saint-Germain for €222 million (S$355 million) debilitated their attack.

They have also attempted to lure French forward Ousmane Dembele to the Camp Nou from Borussia Dortmund but had their bid, reported by German media to be around €100 million, rejected by the Bundesliga side.

The Catalans, who only managed to win the King's Cup last season in a disappointing campaign, face LaLiga champions Real Madrid on Sunday in the first leg of the Spanish Super Cup.
