Brazil legend Rivaldo has urged Napoli midfielder Allan to take the chance to play for Everton if the opportunity arises.
The 29-year-old has been linked with a potential move to Goodison Park this summer by numerous reports, with the Blues keen to strengthen their central midfield area.
However, the ECHO understands Everton are waiting for clarity over the resumption of the Premier League season and the transfer window before pressing ahead with their recruitment plans.
Rumours of a swoop for the Napoli star intensified following the arrival of Carlo Ancelotti on Merseyside in December, with the Italian having worked with the Brazil international at Napoli.
And Rivaldo believes that could be crucial in the player's future.
The former Barcelona forward believes having the confidence of Ancelotti should convince Allan to make the switch if the two clubs do enter business in the coming months.
Rivaldo told Betfair : "I think Allan should take this chance to play in what is, for me, the best league in the world.
"He is a good player who might be useful for Everton. The move would also give him more visibility as he tries to get some more selections for the national team ahead of the Copa America in 2021 and World Cup in 2022
"Having the confidence of Ancelotti is something to be proud of and I'm sure Allan will take this chance of jumping to a more competitive league if the clubs can reach an agreement."
Allan has made 16 appearances in Serie A for Napoli this term, scoring once and bagging one assist from the defensive midfield area.
