The door has opened for Tottenham to sign Philippe Coutinho after Bayern Munich revealed today they will not be activating their option to sign him permanently.

Spurs are among the Premier League big hitters who have asked to be kept informed about the Brazilian superstar’s situation ahead of the window.

A source with knowledge of Coutinho’s situation has told Football Insider that his parent club Barcelona are looking for a buyer and have let it be known that he is available for another season-long loan or a permanent deal at a significantly reduced price.

The 27-year-old has spent the season on loan at Bayern, but chief executive Karl-Heinz Rummenigge revealed today they have opted against the option to make his switch permanent.

That has opened the door for Coutinho to find a new club or return to Barcelona, who are keen to raise funds with a big-money sale as well as get a high earner off their wage bill.

He was signed from Liverpool in January 2018 for a fee rising to £142million but has failed to match the heights of his Anfield excellence.

Arsenal, Chelsea and Everton have also registered their interest in Coutinho, whose price this summer will also be dictated by football’s changed economics.

That could allow Spurs to snap up a genuinely elite talent at a fraction of the price they would normally pay.

Given the squeezed finances, the club may initially prefer a loan deal or a loan with an option.

Coutinho played the best football of his career Liverpool, where he flourished under Jurgen Klopp as the creator-in-chief.

He has had mixed returns at Barcelona – 21 goals and 11 assists from 76 matches – and Bayern, where his 32 games have yielded nine goals and eight assists.
