Sussex bowler Mir Hamza will be a hit once he relaxes

Gillespie believes the Pakistan left-armer put too much pressure on himself on his three-wicket debut in the county's opening Championship defeat by Leicestershire at Hove.

They go to Durham tomorrow with Gillespie confident the Leicestershire game will have been an education for Hamza.

The Australian told The Argus: "He learnt a few lessons. I was chatting to him and I said I know you're excited about being here and he is, he's absolutely buzzing.

"His first class record is incredible. He's played Test cricket, swings the ball both ways at good pace.

"I think it's just quite a big deal for him to have this opportunity to play county cricket and he just wants to impress.

"We are just trying to relax him a little bit, focus on keeping it very simple, bowl your best ball and the surfaces, the conditions, your skill will shine through.

"I almost think he is putting a lot of pressure on himself and trying to make things happen. I fully expect him to perform well, we know what he can do.

"What we saw in the (Leicestershire) game was glimpses of just how skilful he is. There were a lot of positive signs and he is really enjoying himself here. The lads are enjoyable his company and I am sure he will bowl very well up at Durham."
