Leicester Riders guard Cameron Rundles says Great Britain skipper Andrew Sullivan is making a huge impact at the club and he is eager to see him stay.
Rundles told BBC Radio Leicester: "Andy Sullivan has probably made the biggest difference to us with his basketball IQ and his professionalism.
"He's helped in every aspect. Hopefully the club will work things out behind the scenes and he will stay around."
Sullivan has said he is keen to stay but no deal has yet been finalised.
The forward's arrival has prompted an impressive run of form, including the 102-67 destruction of MK Lions in the BBL Trophy last Saturday.
Rundles added: "It was huge game for us we took it seriously. We played one of the best first quarters you could ask.
"It was great game that we played - a great team effort and things are looking up for us right now."
Riders are away against Guildford Heat on Saturday, and despite their winless start to the season, Rundles said that Riders cannot afford to be complacent.
"There won't be any easy games in the BBL. Rob Paternostro [Riders head coach] does a great job getting us prepared," Rundles said.
"A team that doesn't have a win will be really hungry and ready to get us so we have to prepared."
