AC Milan have confirmed the return of Kaka on the last day of the transfer window but the Brazilian is not the only player being linked with a switch to San Siro
Attention has been centred around Adriano Galliani’s attempts to sign Kaka from Real Madrid, with a confirmation of the midfielder's return coming early on Monday morning.
Allegri, though, has refused to rule out the prospect of Astori, the 26-year-old defender, from also arriving at San Siro.
Speaking to reporters after his side’s 3-1 win over his former club Cagliari, the coach said: “I think Davide is one of the best Italian defenders in circulation.
“We have good defenders and I am happy with what we’ve got but Astori would be useful for many clubs, so we will see what happens.”
Astori was on the brink of joining Napoli earlier in the summer before a switch broke down at the last moment, while Roma have also been credited with an interest in his signature.
The defender has five caps for Italy and is keen to secure a place in Cesare Prandelli’s World Cup plans, with his Cagliari contract due to expire in the summer of 2015.
Astori has been left out of the Cagliari squad for their first two Serie A matches, including Sunday’s loss to Milan, fuelling speculation that he may still be on his way out.
On the win over Cagliari, Allegri added: “I liked the approach to this game, as we attacked and defended well. It was an important victory, even if we allowed Cagliari a little too much of the ball.
“We made some mistakes and have already conceded entirely avoidable goals so far this season.
“In any case, the week went well with Champions League qualification and this victory.”
