Rashid Khan says he is keen to learn more from coach Jason Gillespie after being reunited with the Australian at Sussex.
Afghanistan leg-spinner Khan, the world's number one-ranked Twenty20 bowler, has signed for the duration of the Vitality Blast, which Sussex are 13/5 to win.
Last winter he was the leading wicket-taker in the Big Bash as Adelaide Strikers, under Gillespie's guidance, won the title for the first time. Adelaide are 1212/1 to win the Big Bash again in 2018/19.
"I had a good time with Dizzy in the Big Bash," said Khan.
"It's really good to be here, back with him. He's really supportive, on the field and off the field, and I think the way he kept us in the Big Bash was amazing. Hopefully there will be lots of new things I will learn from him.
"It's a pleasure to be here. Playing for a county is always a pleasure and a big honour. I'm really excited to finally be here, and I will try my best to deliver well."
In addition to the Afghanistan star, Sussex also include several players with BBL and Indian Premier League experience in Luke Wright, Chris Jordan, Tymal Mills and Jofra Archer.
"I think we have a very good combination, a very good team - as a batting unit and a bowling unit," Khan added.
"We just need to work together, believe in each other and support each other and hopefully we will go well."
