Toronto FC head coach Greg Vanney has urged his side to cut down their amount of defensive errors.

The Reds lost 3-2 to Chicago Fire on Saturday, their third defeat in a row having conceded two goals or more, and now Vanney is imploring his players to show more care at the back.

"There are just too many simple mistakes," Vanney told reporters Wednesday after training.

"And they're compounded mistakes. It's not one mistake that's giving up the goal; it's three, four, five mistakes on top of each other that are leading to us giving up goals."

Vanney added: "We've allowed too many goals and too many of what I would call fairly easy goals because we've had the right number of people around the ball and the play to deal with it, and we haven't."

TFC will be looking to produce their first shutout of the 2015 MLS season when they return to action next weekend after their bye week.
