The centre-back played a crucial part in the Chairboys 1-0 win over Fleetwood on Saturday and finished the match with a bloodied nose from marking Cod Army striker Jon Parkin.
"Dave Winfield had a huge battle with Jon Parkin and Jon Parkin must have a lot of respect for Dave Winfield now," Ainsworth told the club's official website.
"He bullies a lot of people and is a big unit. He's done that all of his career and made a very good career out of being a big target man.
"Dave gave as he good as he got and some. He came off with a big gash on his nose and I saw at the end of the game that they shook hands and said 'good battle', which is fantastic to see.
"It was two warriors out there, giving it their all. I've told the lads to have a look at Dave's face, that's what it takes to win a game and that's what he has done for us.
"It was awesome. The way he leads the team typifies us."
