The Brazilian is one of a host of players being linked with a move to the Magpies should their takeover go through.
Odds have tumbled on Philippe Coutinho returning to the Premier League, with the unlikely destination of Newcastle United being touted by bookies.
Major British bookies, 888sport, Sky Bet, and Unibet have cut odds from a lofty 66/1 into 6/4, with money continuing to be placed on the move.
At 6/4, that means bookmakers are predicting a 40% chance that the Brazilian dons the black and white stripes next season.
In the last 24 hours, 61% of all bets on Coutinho’s next club have backed the Toon, with 22% of all bets over the last week backing the transfer.
Other bookmakers in the UK are offering longer prices on the transfer, with BetVictor at 8/1 and the best price coming from Betfair and Paddy Power at 10/1.

Elsewhere, Chelsea are the current favourites to sign Coutinho at 5/4 best price, followed by any German club at 3/1.
Tottenham follow next in the market at 8/1, followed by Liverpool (8/1), Leicester (9/1), Manchester United (10/1) and Arsenal (16/1).
The 27-year-old, currently on loan from Barcelona, didn't feature in Bayern Munich's win at Union Berlin at the weekend as he recovers from an ankle injury.
Oddschecker spokesperson Callum Wilson: "The pattern is emerging: Newcastle United are about to be linked with everyone under the sun.
"Philippe Coutinho is the latest star seemingly destined for St. James' Park, and with immeasurable riches soon to be at the Magpies' disposal, it's too early to count this one out just yet."
