AC Milan coach Massimiliano Allegri admits his attack is giving him headaches.

Only Zlatan Ibrahimovic is scoring with consistency.

"I'm sure that all the strikers will start scoring - Alexandre Pato and Robinho will get goals," said Allegri.

"However, it's a good sign that the midfielders are scoring. The midfield has produced 13 goals already and we're not even at the half-way stage yet."
