Everton manager Roberto Martinez admits West Ham counterpart Sam Allardyce may sometimes be criticised for his methods but fans have to accept he "guarantees" results.
This season Allardyce has added a more attacking element to his style to capitalise on the summer signings of Enner Valencia and Diafra Sakho and that has taken the Hammers into the top four.
The former Bolton boss has long been associated with a more direct brand of football which brought criticism from his own fans last season, when they finished 14th. However, that appears to have been forgotten as wins against Manchester City and Liverpool have helped the side into the Champions League places.
"Sam is a very experienced manager who has been in this league for a long time," said Martinez ahead of their meeting at Goodison Park today.
"What he has done with West Ham this season is find a good balance of a side who can be difficult to play against but still really threaten in dead-ball situations but now they have brought in flair and players who can score goals out of nothing from open play and that is a really strong combination.
"There are many styles you can play and it is up to fans to like or dislike that. Winning is important; for certain people in the game the only thing that matters is the result, for others who are a bit more romantic they appreciate more the way you win or the way you want to play than just the short-term result. I think it can be a really successful year for West Ham."
