I think Laca will stay on and might have an extension ( maybe short), otherwise why is he featured regularly in pre season build up. I believe he has qualities which cannot be found in other available strikers ( not talking about Ronaldo, Griezemann or even Kane types, who live in stratospheric levels).
He should be kept even at the risk of losing for nothing next season. Remember the RVP saga? If we were a little brave and kept him on, we could've pipped ManU to the title. He was the Difference, that year.
