IN-FORM David Wiese wants to see a complete team performance from Sussex today - whether they make the Royal London One-Day Cup knockout stages or not.

The odds are stacked against Sussex reaching the quarter-finals as four counties fight for the two remaining places but a win in front of the Sky cameras against Glamorgan at Hove is essential if they are to have any chance.

A quarter-final spot would be secured if the Sharks beat Glamorgan, and two of Gloucestershire, who face Essex, Somerset, who host Surrey, and Middlesex, who travel to Kent, lose.

Otherwise, the Sharks would have to beat their Welsh visitors by a big margin and hope there is an unlikely swing in run-rate.

Wiese has done as much as anyone to keep Sharks in the fight and has amassed 338 runs across six innings including a record-breaking 171 in an agonising defeat at Hampshire.

He top scored with a 58-ball 55 in Sunday’s disappointing defeat to Gloucestershire at Eastbourne too which saw Sharks’ hopes suffer a massive blow.

Wiese reckons Sussex find themselves in this predicament because they have not managed to put it all together as a team in the 50-over competition.

The South African all-rounder said: “If you look at the whole campaign, we have been lacking in putting in the complete team performance.

“Every time we have won a game it has been when someone has stood up and put in a match-winning performance.

“That’s fantastic for a team when you have different guys stepping up and putting in those performances but cricket is also a team sport and not just individuals. Sometimes you need to gel as a team.

“I just feel that we haven’t been able to put in that complete performance, which is disappointing because at stages everybody has shown they are in-form and playing well.”

He added: “It is another opportunity (today), it’s a Sky game at home and hopefully people come out and support us.

“It’s an opportunity to show off our skills and hopefully put in that complete team performance and get the win under our belt.

“We need to do everything we can do from our side and hope things go our way.”

Wiese certainly has clicked though, with his 171 knock at the Ageas Bowl breaking Luke Wright’s record of 166 - which was set at Lord’s just five days beforehand.

The 33-year-old said: “So far so good. It’s been a strange competition.

“I’ve been given more responsibility and moved up a bit in the batting line-up and, as things have worked out, I’ve had opportunities to bat quite a bit of time out there.

“It’s been nice to spend time in the middle because throughout my career I haven’t had that kind of opportunity before. Thankfully it has worked out for me and I’ve enjoyed the campaign so far.”

Wright did not get long to savour beating Chris Adams’ one-day record set in 1999 - but Wiese admits he did not even realise until later the significance of his innings.

He revealed: “I was caught in the moment and walked into the changing room, sat down and watched the end of the game.

“Wrighty quietly came over and shook my hand and said ‘congratulations you’ve just smashed my record’. That was the first time I realised and we had a little chuckle afterwards that it took so long for someone to do it and then his stood for two games!

“It’s just the way the game works and I am sure someone will come along and get 200 at some point.”

Phil Salt returns to the squad after his time with the England IT20 squad.
