Team GB star Chris 'Bomber' Harris insists it is all or nothing in tonight's World Team Cup event two at King's Lynn. (7.30pm).

Harris hopes the Lions can defeat a slightly weakened Polish team, a depleted Russian side missing former World U21 champion Emil Sayfutdinov and a beatable Czech outfit to book their place straight through to the final at Gorzow on Saturday.

The second and third-placed sides would have to battle out a sudden death race-off at the same venue on Thursday.

'We've looked at it and if we're going to get to the final, realistically we've got to look at winning at King's Lynn,' he said.

'If we have to go to that race-off, getting first or second is going to be really tough, so hopefully we can get to the final here tonight.'

The Poles go into the competition without grand prix star Rune Holta, while Janusz Kolodziej and Krzysztof Kasprzak have both endured extremely inconsistent seasons.

But with world champion Tomasz Gollob, world number two Jaroslaw Hampel and former King's Lynn rider Piotr Protasiewicz in their ranks, Harris knows topping the rostrum at the Norfolk Arena will be hard.

'The majority of the Poles have probably raced on the circuit at King's Lynn, but this is what the World Cup is about,' he said.

'It's about going out and beating the best.

'We've got the world champions in our first round and if we can beat them, it sets us up for the rest of the tournament.'

The Team GB skipper is also appealing for British champion Scott Nicholls to remain with the squad – which features Lynn captain Olly Allen – if they progress to Poland for either Thursday's race-off or final.

The Swindon rider admitted he may have to miss the possible events in Gorzow for family reasons.

Harris hopes the six-time British champion will join him on the plane and help his country win its first World Team Cup medal since 2006, when they finished third at Reading.

With Tai Woffinden, Edward Kennett and Ben Barker all relatively inexperienced at international level, the Cornishman believes Nicholls' presence in the side is vital.

'It's very important. We need Scott in the race-off or the final – whichever one we go into,' he said.

'He has the experience under his belt. He's the oldest one in the team and he has done more World Cups than any of us.

'On his day, he's shown he can beat anyone and score points. We desperately need to keep him in for the whole of the tournament.

'I believe Middlo (team manager Neil Middleditch) is going to speak to him and try to talk him around.'
