Mark Robinson admits Sussex's demolition of Warwickshire in the Pro40 offers no guarantees of success in the Championship.

But it can certainly help their cause when they start their latest four-dayer at Edgbaston today.

Robinson's men were more convincing winners than the 37-run margin suggested when they opened their 40-overs campaign against the Bears at Hove on Tuesday.

Team coaches and managers in all sports are fond of playing down such results when they know they are coming against their vanquished opponents again in the near future.

But Robinson is not taking that line as his team aim to build on their leadership of the Championship.

He would rather use Tuesday's game as a precedent than Sussex's record of 11 wins in 69 visits to Edgbaston.

The Sussex coach said: "Tuesday's result won't do us any harm, will it?

"Historically Edgbaston is not a good ground for us but we need to right a few of the wrongs that have happened here.

"It's another big game but we are getting used to that. We turn up for every game saying the same thing.

"It's really good. It's an exciting part of the season. Every game is a big game, with the build-up and the media interest, and the players are really enjoying that.

"We were really pleased with how it went on Tuesday. It puts down a marker for the next four days but we still need to play good cricket and keep working hard"

Mushtaq Ahmed was being linked Sussex look to punish Bears again after Pro40 with a call-up by Pakistan for the second Test which starts at Old Trafford today.

But that possibility was dismissed by Bob Woolmer yesterday.

The Pakistan coach said: "I've watched cricket a lot here (at Old Trafford) in the last four years and spinners haven't been devastating.

"Shane Warne's figures were 0-74 in the second innings against England last year and he's one of the greatest leg-spinners of all time."

Sussex are getting used to talk of either Mushtaq or Yasir Arafat being taken from them.

Robinson said: "We read speculation about one of them being called in but we have heard nothing."

Mushtaq and Chris Adams missed the Pro40 win over Warwickshire but are in the 12-man squad which travelled to Birmingham yesterday.

Jason Lewry also returns. Sussex will decide which of their seamers misses out after inspecting an Edgbaston pitch reported to be very green.

Second-placed Lancashire, 13 points behind Sussex with a game in hand ahead of this round of fixtures, began their match with Nottinghamshire yesterday and endured a pretty frustrating day in the field at Trent Bridge after losing the toss.

In-form Australian David Hussey struck a brilliant 150, his second hundred in successive Championship innings, to dig Nottinghamshire out of a big hole.

The hosts had fallen to 107-5 on the first morning before Hussey took control, hitting 22 fours and a six from 177 balls in a classy display of batting.

Hussey made Lancashire regret dropping him on two, when Dominic Cork put down a one-handed chance off Oliver Newby at second slip.

The 29-year-old shared a sixth wicket stand of 226 with Mark Ealham, who made 83, in a Nottinghamshire record against Lancashire.
