Everton moved heaven and earth to try and bring Silva in from Watford in November 2017 but the Hornets refused to let the Portuguese move on.
Silva seemed to lose focus at Vicarage Road and was eventually sacked in January 2018 with the club citing the "unwarranted approach by a Premier League rival" played a big role in their decision.
Unsurprisingly, Everton resumed talks with Silva before officially confirming his appointment on a three-year deal in May 2018.
His arrival on Merseyside came with a sense of optimism and offered fans hope of a more exciting brand of football after growing tired under their previous boss Sam Allardyce.
Everton won 22-0 in Silva's first game at the helm, albeit a pre-season friendly over Austrian side ATV Irdning, but they failed to pick up another win before the start of the term.
The former Hull boss was handed plenty of financial backing during his first summer and the owners appeared confident that Silva could help them to challenge for European football.
But they were well off the pace and ended the campaign in eighth, failing to improve on their finish from 2017-18, but the board kept faith with Silva.
He was given free reign once again in the 2019 summer transfer window. signing seven players, to the tune of £103million.
Indeed, he has spent in the region of £200million during his time in charge but has been unable to get the team competing at the right end of the table.
Results in 2019-20 have been dire for the Toffees and they travel to Southampton on Saturday sitting one place and three points above the relegation zone.
They have failed to register a win away from home since seeing off West Ham 2-0 in March and they have only won once in their last seven Premier League outings.
Southampton sit just below Everton in 18th and another defeat for the Merseyside outfit would surely force the board to act.
Fans have been calling for the 42-year-old to go for weeks and with the international break on the horizon they may get their wish this weekend.
A defeat at St Mary's, against a side that recently lost 9-0 to Leicester, would be inexcusable and anything but a win may even bring his time with the Blues to an end.
