We have to be at the top of our game:
Punjab coach Darren Lehmann said his team will have to be at the top of their game if they are to defeat a ``quality'' Mumbai side.
``Look at this stage I don't know who we will play in the final but on Thursday definitely it is going to be a tough game for us and we need to carry on our form and momentum in the competition for the final,'' Jayawardene said.
