Lazio boss Edy Reja knows their top four hopes are on a knife edge after defeat to Juventus.

Now Lazio have only a one-point lead over Udinese - their next opponents - and Roma, with Juventus four behind.

"It is certainly decisive on Sunday against Udinese, but all things considered we're in good shape and after that game will have a better idea of what we can achieve," said Reja.

Lazio lost last night to a late Simone Pepe effort from Juve.
