"You never believe you are a great leader, until actually you have success in lifting a trophy. That's when you finally believe you have done a great job. He too has got that in him and hopefully he achieves that goal. He is on the journey."
The former Australia opener also backed Karthik to bat at No. 4 in the World Cup beginning May 30.
"He's very consistent. There's no doubt he has done the job of a finisher when he got an opportunity. He can potentially bat higher. There's a lot of talk around that No. 4 spot and he's the sort of guy who likes to spend some time in the middle," said Katich.
"Once he is set, he is very hard to bowl to at the back end of an innings. He has got all the tricks. He also has got the timing and and power to clear the rope particularly off the short ball. He played a couple of hook shots for sixes in Delhi," he said of Karthik's 50 against Delhi Capitals.
That's Karthik's only half century this IPL season as he has just 111 runs from seven innings at an average of 18.50 -- a far cry from last season when he was KKR's leading run-getter.
"He's been in great touch but not getting more opportunity because top order batsmen are doing their job," Katich said, insisting that Karthik's form is not a concern for KKR.
After suffering three successive losses, KKR next face struggling Royal Challengers Bangalore at Eden Gardens on Friday.
Having lost seven matches out of eight, bottom-placed RCB's playoff hopes are all but over and Katich said the Virat Kohli-led side have not been able to combine well as a team.
"It's easy to talk from the outside. Until you are in the inner sanctum, you don't know the mood, the group. That's probably the hard part. They have not been able to gel as a unit," he said of RCB.
On Kohli's captaincy, he said: "It's hard to judge his captaincy. Only those within the team will know that. He's probably still learning. A fantastic player in all formats but leadership is something that can be developed over a long period of time. So he is still in a phase where he is learning a lot about himself as a leader.
"He has got everything covered as a player, he is going to go down as one of the all time greats. There is no doubt about that. As a leader, he has got attributes like passion and energy he brings to the team, India and RCB. He wants to win and has got a strong desire to succeed which is what you need as a captain."
Katich said in the World Cup, Kohli will be better as he will get inspiration from Mahendra Singh Dhoni.
"He (Kohli) is learning from one of the greats (Dhoni).
