During the night to Tuesday came the message that the Portuguese has done his thing in Nottingham Forest.
"As someone who played a significant role in our success last season, he will always hold a special place in our journey", writes Forest on their website.
Forest finished in seventh place last season, which was the club's best placement in decades and was enough for a Europa League spot.
According to reports, Espírito Santo has fallen out with Forest's owner Evangelos Marinakis. They are said to have disagreed, among other things, about this summer's recruitments and the club's development.
This season, Nottingham Forest has taken four points in the first three rounds and is tenth in the table.
