Lazio coach Vladimir Petkovic wants his players to stay grounded as they move into third place.

The Biancocelesti have been a revelation this season and lie in third place behind joint leaders Juventus and Napoli.

"We have to keep our feet on the ground. We have done well, but are also aware we are not 100 per cent. We always want to keep control of the game, which isn't easy, but so far the players have worked hard and shown some pretty positive things."
