England bowling consultant Tim Southee admitted on Thursday it will be "a little bit strange" to be in the opposing change room to New Zealand at the T20 World Cup.
The winner of the England-New Zealand clash at Colombo's R. Premadasa Stadium on Friday will secure top spot in Super Eights Group 2.
England have secured a semifinal place, whereas New Zealand need a win to be sure of a place in the final four.
A defeat will leave them having to rely on Pakistan failing to beat the already eliminated Sri Lanka by a big margin on Saturday.
Southee played 394 times in all formats for New Zealand and took 391 wickets in 107 tests.
"It is a little bit strange seeing the guys around the hotel and obviously with that series in New Zealand end of last year," Southee said.
"It's a great opportunity to work with England.
"I always want New Zealand cricket to do well, always following them closely, but now in the role that I'm in, things are slightly different.
"I'm looking forward to going out there against a good side and some good mates as well."
Southee said he has enjoyed working with Jofra Archer, who has grown into the tournament.
The express paceman conceded 98 runs in his eight overs in the first two group matches.
But he took 3-20 against Sri Lanka and 2-32 against Pakistan in England's two Super Eight games, regularly sending down deliveries around 150 kph (93 mph).
"The good sign is that we've seen over the last few games he looks like he's getting better and better so that bodes well for the next few games," Southee said.
"He's obviously a class bowler. He can bowl fast, move the ball and he has an unbelievable amount of skill.
"It's been brilliant to see how he goes about his stuff. He absolutely loves cricket, loves bowling, so it's been great to work alongside such a great bowler."
