Marco Silva's agent Carlos Goncalves believes success is built gradually but admits results will define his client's career at Everton.
Everton currently occupy a position in the relegation zone following defeat to Burnley on Saturday and Newcastle United's victory over Manchester United the following day.
And Goncalves, speaking to Record via Sport Witness, was asked whether Silva's position as manager could be under immediate threat.
“Any coach depends on the results," he explained. "We signed a three-year contract and football, with the entry of investors, makes us want immediate success, when success is actually built gradually.
"The English coaches, who [managed] 10-15 years at the same club, disappeared.”

Goncalves also opened up on Silva's original move to Hull City in 2017.
The Tigers were eventually relegated under the stewardship of the Portuguese boss before he eventually joined Watford the following summer.
"Marco always had that ambition and hence took the risk, gambled in January and went to the condemned Hull City," he added.
"The club eventually were relegated but the work he did was unanimously well received. So he had four invitations to stay in the Premier League and moved to Watford.
"I think all coaches have this ambition, because it is the most competitive championship in the world and where the best are.”
