Bologna prospect Mantovani in Rangers sights
Former Italian international Giancarlo Marocchi, now involved with Bologna's youth academy, admitted they will find it difficult to hang onto Mantovani.
"He is good, but we can't lock down all the promising youngsters. Unfortunately, with the rules here, we can't put all our promising kids on contracts to keep them away from foreign clubs. We have no weapons.
"But hopefully he will decide to stay with us."
