Royals are currently at seventh place in the eight-team points table.
Having won 4 out of their 11 games, Royals are currently at seventh place in the points table.
The Steve Smith-led side will take on table-toppers Mumbai Indians (MI) in their next game in Abu Dhabi on Sunday (October 25).
"It's hard for us to really identify one area where we went wrong. Clearly, we haven't been at our best consistently and ultimately that's what it's about in these tournaments. It's such an even tournament and the challenge is to bring your best out in every game and unfortunately, through the course of the tournament, we haven't done that and have allowed teams to come back in games we probably should've won," McDonald said in an official release issued by Rajasthan Royals.
"Our destiny is probably in other teams' hands now and as for us, we need to keep believing, our challenge is seven wins and we'll try to give our best to achieve that," he added.
Rajasthan Royals had suffered a comprehensive eight-wicket defeat in their last outing against Sunrisers Hyderabad (SRH).
On the other hand, Mumbai Indians will come into the game on the back of a resounding 10-wicket victory over Kolkata Knight Riders (KKR).
When the two teams faced each other earlier in the tournament, MI emerged triumphant by 57 runs.
