The Kenyan midfielder, this week named the SPL's young player of the year, has yet to sign a new deal with just a year of his contract to run, while his manager has been linked with the Everton job following David Moyes's switch to Manchester United.
Wanyama remains coy on his next move but believes club chiefs should do all they can to make sure Lennon stays put.
He said: "I just leave the club and my agent to sort everything out. You never know. We will see."
On Lennon, he added: "He has been great. I've learned a lot from him. He has put a strong team out there and he is still a very important manager for us.
"I would say he is one of the best managers I have had in my career.
"We have learned a lot and we have achieved a lot while I have been here. We are delighted to have him.
"There is no doubt other clubs want him. We all just want to see him stay here."
