Sam Allardyce has been criticised for his style of football at Upton Park but Jaaskelainen says he doesn't care how the team play as long as they are winning.
"The criticism Sam receives doesn't puzzle me because you go out to win every match," said the Finn, who has won 56 senior international caps. "To do that, you have to play in different ways, employ different methods.
"I'm just glad when we win a match. I'm not worried about the style."
