This seems like a move we'd make. Tevez is a great striker now and for a couple years but we have a chance to get him at a discount. He's a stop gap type player that would satisfy Conte's requirements and also not require a huge financial commitment upfront which is what we like since we are undergoing the Continassa construction and are funding that with mostly cash.
Tevez can hopefully keep up this level for 2 or 3 years and then depart. Meanwhile, we'd have increased annual revenue by a large amount by then, hopefully, and would have more cash available yearly to fund a truly top striker or two.
