Lacazette is once again set to be courted by Europe's top clubs this summer after Aulas held on to the France striker last year.
Arsenal had a £29.3million offer rejected but are reportedly set to renew their interest in the 25-year-old.
While Lacazette's compatriot Griezmann is also coveted by Europe's biggest clubs.
The Atletico Madrid striker is wanted by Manchester United and Real Madrid and has a £86m release clause in his contract.

But Aulas appears to believe if Griezmann is worth £86m, Lacazette should command a similar fee.
When asked what he would sell Lacazette for he told French newspaper Le Progres: “We have rejected offers worth around €40m. I am hearing talk about €100m for a Griezmann transfer to Real Madrid.”

In February, Lacazette said he felt he'd reached the "right moment" to leave Lyon.
He said: "I think that the right moment has arrived to leave. I think that this summer I will need a change of scenery and [to] discover something else, still with the idea of advancing and progressing in terms of football and as a person."
