Kolkata, Apr 26 (UNI) Ajinkya Rahane urged his side Kolkata Knight Riders to "live in the moment" and play positive cricket ahead of a crucial encounter on Saturday, even as opposition Punjab Kings (PBKS) skipper Shreyas Iyer chose to bat first after winning the toss.

Speaking at the toss, Rahane admitted the team had been patchy and called on the batting unit to step up.

"It's all about playing good cricket, need to chase down whatever the target is," Rahane said.

"Our bowlers have been bowling really well. They have improved a lot. The boys have disappointed with the bat, but need to be brave in this format. Our batting unit needs to do well in this game. It's all about living in the moment and being positive."

Rahane confirmed two changes to his side, with Rovman Powell replacing Moeen Ali and Chetan Sakariya coming in for Ramandeep Singh.

Meanwhile, Shreyas Iyer said his decision to bat was based on the condition of the surface.

"We are batting first. Since we are playing on the same wicket they played on, can see a few cracks, will get an idea on how it's playing," Iyer said. "It's always been great to play in front of this crowd. Another day to come here and embrace."

The PBKS Captain underlined the importance of seizing key moments, especially with the ball.

"We have been getting brilliant starts. We are talking about a few situations, need to play to our best ability and believe in ourselves. I want the bowlers to take wickets, it changes the momentum. The more wickets we take in the powerplay, gives a chance to the other bowlers."

Shreyas also announced two changes, with Glenn Maxwell and Azmatullah Omarzai coming into the playing XI.
