Scott Brown has backed Celtic to overturn their three-goal deficit against Legia Warsaw in the second leg of their Champions League qualifier.
The Polish side beat the Scottish champions 4-1 last week, and play the second leg on Wednesday.
The Hoops captain, who is currently sidelined with a hamstring problem, told Sky Sports News: "It's going to be hard because we need three goals but I believe we can do it. The Shakhter game last season was huge for us, we scored three goals then and we have to do it again this week.
"It always hurts when people write you off, but that's football. People always write you off. That's when you have to put the wrongs right and go out there and show everyone what you can do. You can prove a point to everyone out there on the field."
Celtic reached the group stages last season after needing a 3-0 win against Shakhter Karagandy in the final qualifying round.
