The agent of Everton boss Marco Silva remains confident he can be successful at Goodison Park.
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.
Carlos Goncalves told Record: "Any coach depends on the results.
"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.
"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."
