David Wiese admits it has been difficult to adjust to not playing as regularly for Sussex this season.

The 36-year-old all-rounder had previously played for Sussex under Kolpak registration- which gave sportsmen from countries with associate trade agreements with the European Union the same rights as EU workers.

However, Kolpak registrations have now been terminated following Brexit.

That meant Sussex had to sign Wiese one of their overseas player.

However, he can only play in white-ball cricket due to Sussex already having two other overseas players as part of their County Championship squad in Stiaan Van Zyl and Travis Head.

But Wiese admits it has been tough for him to go months without playing.

He told The Argus: “It is a bit of a tough one because you are on the sidelines for two to three months at a time and then you suddenly have to come in and hit the ground running.

“Especially this year with the weather, there was not a lot of opportunities to train before the game because the facilities were just wet and it was quite rainy.

“So, I came over quite early to do a bit of work before the season and it just didn’t work out that way.

“But it is tough sometimes when you have almost got to take two or three sessions before the season starts and then go and try to do your best.

“Ultimately we are professionals and that is what you have to do and you have just got to make it work.”

Wiese has so far struggled with the bat this season scoring just 71 runs from his seven innings in the T20, and 50-over game combined.

However, in his first match in the Royal London One Day Cup, the South African was denied the chance to get his first big score of the campaign after he went for 27 thanks to a magnificent catch by Scott Currie at wide mid-off in their defeat to Hampshire on Tuesday.

But Wiese hopes runs are just around the corner for him.

He said: “It has been a bit of a tough one coming back and only playing white-ball cricket, you have got to hit the ground running. Unfortunately for us, it has been a bit of a stop-start season with the weather, it has been difficult to get any momentum going.

“So, for me personally I have struggled a bit, I haven’t put in the performances that I would like to.

“But in saying that we have made it through to the quarter-finals of the T20 and have still got a couple of games left if we make it through to finals day.

“There is still a lot of time to put in some big performances, so far it hasn’t quite gone to plan for me but I am still feeling good, feeling positive out there, and hopefully runs are just around the corner.”

It is not just Wiese who has struggled so far this season, Sussex have also had a mixed start to their campaign.

They sit bottom of Group Three in the County Championship and have lost two of their opening three matches in the Royal London Cup.

However, they are in the quarter-finals of the Vitality Blast next month when they face Yorkshire at Chester-le-Street.

But Wiese believes Sussex’s tough start to the 50-over competition has to be put in perspective with the number of young players involved.

He said: “I suppose if you look at it results-wise it has not been the greatest start, but you have got to put things into perspective.

“If you look at the first game there was nine list A debuts, we have got 16 and 17-year-olds playing in the side at this stage, which is great for the development of Sussex cricket and the future of the club is looking very bright.

“But these guys are still kids and need time to develop.

“I played in the last 50-over game and there is so much potential floating about and they are still so young.

“So, if you look at it results-wise it is not a great start but there have been a lot of positives in the last two games.”

The number of players being given their debuts has been partly down to the fact that Sussex are without nine key players.

Eight of those are competing in The Hundred in Tymal Mills, Luke Wright, Phil Salt, Ravi Bopara, Rashid Khan, George Garton, Chris Jordan, and Delray Rawlins.

Seamer Ollie Robinson is also away with England after he was recalled to the test squad.

However, Wiese admits Sussex knew they would find it difficult without some of their key players.

He said: “We knew it was always going to be tough as soon as The Hundred came out because we have got such strong white-ball squad, so we knew most of those guys were going to be picked up.

“But in saying that it has allowed us to give opportunities to these youngsters to learn their game, to see what they are all about and for themselves to see what it takes to play at this level.”

Sussex host bottom-of-the-table Kent in the Royal London Cup at Hove this morning (11am), but Wiese knows the visitors will be tough opponents despite their league position.

He said: “Kent are a quality side and they have also lost a couple of players to The Hundred.

“But they have still got a lot of quality guys and they have got a lot more regular first-team players in their side.

“So, it is going to be a tough one, they have shown in the T20 campaign that they are a top white-ball team and it is going to be a difficult game.

“But again, it is an opportunity for someone to show up, show off their skills, and for the youngsters to gain more experience against some of the top players.”
