The Brazilian has struggled to settle in Camp Nou since his £ 142 million transfer from Liverpool in January 2018.
Despite an impressive loan period with Bayern Munich this season, his future is still far from Barcelona, and Coutinho’s agent has escalated rumors by saying earlier this month that he “would like” to play Premier again League.
And the door was opened for Coutinho to return to England thanks to Bayern Munich which did not activate an option of 120 million euros (105 million pounds sterling) to buy the midfielder at the end of his loan in Germany.
Once Chelsea learned of this, they contacted Barcelona to start negotiations for a fee, according to Spanish media Sport.
The report adds that Blues boss Frank Lampard is a team for the 2020-21 season who will be able to compete with Liverpool and Manchester City at the top of the Premier League.
However, it is expected that negotiations will be extended as clubs reduce Coutinho’s fees.
Barcelona are reluctant to let the 27-year-old leave the club for considerably less than two years ago and aim to sell for as much as € 90 million (£ 79 million).
Meanwhile, Chelsea don’t want to spend as much on the player and think they can negotiate lower fees based on Coutinho’s desire to return to the Premier League and Barcelona’s need to raise funds for their summer transfers.

The Catalan club is said to have provided a busy window in which it will bring Neymar back to the club from Paris Saint-Germain and sign Inter Milan star Lautaro Martinez.
Neymar left the club in 2017 for £ 198 million and Lautaro Martinez has a release clause of 111 million euros (£ 98 million), so any deal for the two stars will cost hundreds of millions of pounds.
