Kolkata Knight Riders' loss toAuckland Aces in a Champions League Twenty20 match left New Zealand batsman Brendon McCullum with mixed emotions as on one hand, he felt gutted for his IPL champion team but on the other, he was glad to see a New Zealand side doing well.

"They were the enemy today, but from a New Zealander's point of view, it's a good thing that a team from there does well," McCullum said after KKR's seven-wicket loss to the qualifiers here.

"They've dominated the domestic T20 competition for the last two years and have spent plenty of time here in preparation.

"They're playing some excellent cricket. It's great to see from that they are winning games in this tournament and hopefully New Zealand's involvement in CLT20 continues."

Reflecting on his team's performance, McCullum said KKR have not yet realised their full potential.

"We're starting off very slowly and also the conditions are very different from back in India. We've failed to get all three aspects of the game together so far.

"But we're not out of the competition yet; we need a certain things to go our way and we'll play a lot better in the next two games. We're not quite there at the moment," he said.

"We've got two big games to go and we can't be too harsh on ourselves. That will only make it more difficult for us to improve our game in the coming games."

McCullum defended the decision to leave out speedster Brett Lee despite the conditions being pace-friendly.

"Brett would've bowled very well on this wicket but we have the constraint of playing four overseas players, which makes it a bit tough to find the right balance.

"We were looking to shore up our batting with Shakib in the team. Shakib's an excellent player as well. But it's one of those things that we'd have done differently in hindsight."McCullum said it is tough for the batsmen to get going on tracks here.

"These are pretty trying conditions. Sometimes, on wickets like this you do need a little bit of luck and unfortunately we haven't had that in the first two games. Even very good batsmen can be susceptible on these wickets," he explained.

Asked to what extent was Jacques Kallis's lack of form hurting the team, McCullum said, "Jacques was injured last game and retired hurt. Today the way he got out (outside edge to Azhar Mahmood's in-swinger) only he could've nicked that ball ? he's so good. I'm sure he'll be among runs in the next two games. His bowling has been outstanding."

In the meantime, Vincent revels in revenge over KKR:

Auckland Aces opener Lou Vincent said the win over Kolkata Knight Riders in a Champions League Twenty20 match here was long-awaited sweet revenge for his side after the IPL team had shunted it out of the event's last edition with narrow victory.

Auckland beat KKR by seven wickets last night to extract revenge for the two-run loss in the 2011 CLT20 qualifiers that set the Kiwi team packing.

"We had unfinished business from last year when we lost to them. We got one against them and did our job today", Vincent said after his side came out trumps with 14 balls to spare with a commanding performance.

Talking of his own form with the bat, Vincent said, "I'm getting the team off to a good start but hope to do better in the coming games by playing right through the innings."

"Had I batted 20 overs, I'd have scored 200, wouldn't I?" quipped the player who made a 12-ball 30.
