Tottenham Hotspur manager Andre Villas-Boas has hailed David Moyes for his impact on Everton since his arrival at Goodison Park in 2002.
The Scotsman led the Toffees to fourth place in the Premier League in 2005 and has only finished outside the top eight twice during his nine full seasons in charge of the Liverpool outfit.
"He has done tremendously well," said Villas-Boas. "He has changed the mentality of the club. They went through incredibly difficult situations financially and has always built strong teams.
"His scouting is perfect, his training is perfect, the way he motivates his players also makes a difference as you see them on the pitch and they are extremely competitive.
"His teams always seem to improve year after year and that is not always the case. Going to Goodison Park is one of the toughest games."
Everton host Spurs in the Premier League on Sunday.
