With Roberto Martinez's tenure at Everton looking increasingly uncertain rumours are starting to circulate about possible successors to the Spaniard at Goodison Park.

Everton have reportedly sounded out Marcelo Bielsa as Roberto Martinez's potential successor, according to @brunoandrd #EFC — Richard Buxton (@RichardBuxton_) April 10, 2016

Brazilian journalist Bruno Andrade claims Everton have approached former Argentina and Chile coach Marcelo Bielsa about the possibility of taking over at the Toffees.

It is claimed that the 60-year-old, who has been out of work since quitting as Marseille boss last August, is keen on a move to the Premier League next season. He is believed to have held talks with Swansea in December but no deal materialised.

Bielsa wants to come to England next season, and has rejected offers from Brazil, Argentina and Spain. He was happy with Everton's approach. — Sán (@Zizouology) April 10, 2016

Bielsa would also be something of a left-field choice, given he has never managed in England before. The prospect of his famous 3-3-3-1 formation, so successful with Chile and Bilbao, being implemented on the Everton squad is an intriguing one though.

There isn't much else to go on than that, so these rumours need to be taken with a pinch of salt. But is certainly is another reason to believe Martinez won't be in charge next season - even if we go on and win the FA Cup.

It is also a good excuse for someone to have fun on Wikipedia:
