Sartori discusses Rowe, Lucumi situations at Bologna

Rowe left Olympique Marseille for Bologna in a €17m deal.

Sartori said: "I have to say that a very significant investment has been made. We hope he gives us what we all expect."

Meanwhile, Sartori also admits they want to secure Jhon Lucumi to a new deal.

The Colombia defender came close to joining Sunderland over the summer, but ultimately stayed.

Sartori added: "He's a great player, we hope he stays with us for a long time."
