Fiorentina coach Cesare Prandelli has played down the omission of Arturo Lupoli from their UEFA Cup squad.

The former Arsenal man wasn't registered for the competition by the Viola and Prandelli explained: "Unfortunately I only had 22 slots at my disposal and we had to exclude a few others as well. Arturo needs to work to improve every aspect and he will become a great player.

"We could have had a little more luck with the draw. Groningen are a good side who know how to play football and are very organised tactically."
