Napoli defender Miguel Britos admits he's frustrated watching from the sidelines as his team fly up the table.

The Uruguayan joined the Naples outfit in the summer, but sustained a broken foot in the team's pre-season friendly at Barcelona five weeks ago.

"It costs me so much to see the successes of my teammates without being able to participate.

"I wish I could play right away, but unfortunately the injury I suffered needs time to heal because the break was in the bone, and so I must adhere strictly to the time needed for it to heal.

"I think a month, and if all goes well I will be available to [Walter] Mazzarri."
