The current Magpies owner Mike Ashley is expected to sell the club amid keen interest from the Saudi and American parties, both of which have made former Tottenham Hotspur manager their priority management goal.
Meanwhile, Coutinho looks set to leave Camp Nou this summer after spending this season on loan with Bayern Munich.
The Brazilian playmaker’s agent said last month that his client “would like” a return to the Premier League, heightening speculation linking Coutinho to a move to Chelsea.
However, the Blues are unwilling to meet Barcelona’s asking price of £ 87m for the 27-year-old and Newcastle has emerged as a contender thanks to Pochettino’s admiration for the former Liverpool man.
Spanish outlet Mundo Deportivo reports that a previous approach for Coutinho by Pochettino has been blocked by Spurs president Daniel Levy and that the Argentinian coach could dive again.
“Pochettino already tried last summer to sign Coutinho for Tottenham and if he did not succeed, it is because of President Levy’s irreparable enmity with the Brazilian agent,” the report said.
“Now, with no personal problems involved, Coutinho could reach a club for which, in recent months, [Antoine] Griezmann also rang. ”
A Coutinho or Griezmann marquee signature at St James ‘Park would be a declaration of intent for a Newcastle under new property.
The report added that Pochettino “would become the leader of a project, such as the one in which Manchester City started, and which wants to place Newcastle in the football elite.”
