Sinner has work cut out to topple Wimbledon king

...but England's U21s face big ask

BACK Liam Delap to bring the heat as the Club World Cup reaches the last 16.

The new Chelsea striker has been relatively lightly used in the USA, but with Nicolas Jackson banned the 22-year-old should be front and centre from the get-go against Benfica (9pm UK time) in the first round of knockout games.

Delap spent last season tirelessly running around in a lost cause with Ipswich, and there will surely be no more up-for-it player on the pitch.

‘The 21-10 (Unibet) about ‘Delap anytime scorer’ (90mins) is not miles off his raw Prem numbers for the sorry Tractor Boys, and will add a bit of armchair interest.

‘Throw in some ‘Delap is shown a card’ at the 19-5 (Unibet) - that’s chunky on his bookings data.

You can watch the match for free live on DAZN as our friends at Channel 5 are going with 90 minutes of ‘The Secrets of Diana's Wedding Dress’ instead, which sounds like a similarly brutal test of stamina.

‘The extreme heatwave conditions for the CWC are already having an impact on performance - fatigue, cramps and the pressing need to keep up the fluids have sometimes made it a challenge to get to half-time without falling off the sofa exhausted, and it can’t be much fun for the players either.

Now in the knockout phase we've got to factor in extra-time and penalties in temperatures where even a round of rock-paper-scissors might stretch enthusiasm.
