Wolves technical director Scott Sellars has said the club needed to retain Joao Moutinho's presence in the dressing room.
The 35-year-old midfielder signed a one-year extension with the Molineux outfit on Monday.
He said: "In Joao's time at the club, he's been vital, bringing real experience and quality to the group, so to get him resigned is a massive boost for us all. With contracts, it's about getting to a place where everybody's happy, the club and the player, and it isn't always easy, but in the end what matters is the outcome and we're very happy with it.
"He's a huge influence in the dressing room, with the younger players, and sets standards that they follow. His and Bruno's (Lage) relationship is very important. As a coach, you like players who can solve things on the pitch, and Joao is certainly one of them."
