Jose Mourinho's record of success proves that he will turn things around after a difficult start at Manchester United, says assistant Rui Faria.
Sunday's 1-1 draw against West Ham means Mourinho side are sixth and 11 points behind leaders Chelsea - they were second and had 27 points at this stage last season under Louis van Gaal.
"It's a big club and we are used to big clubs - we also know how to take a team to win," said Faria.
"We know that we will do it."
Mourinho won three Premier League titles during two spells at Chelsea, who sacked him last December as they lay 16th, having lost nine of their first 16 league games.
