Claudio Marchisio warns Juventus “the dropped points are starting to weigh on us” after a fourth draw in five games.The Bianconeri were twice leading last night, but pegged back to a 2-2 result by Genoa in Turin.“Now the dropped points are starting to weigh on us,” said the midfielder.“We cannot take the lead and then close down hoping the game will come to an end the way we did tonight. “We had scoring opportunities, such as Giorgio Chiellini’s two headers and Mirko Vucinic in good positions. When these situations occur, we must make the most of them.“We’ve got to be more clinical and finish off matches. It’s also crucial we maintain the tempo for 90 minutes. We’re still in time to improve, especially as the progress from last season has been notable.”Juventus are top of the table, although Udinese could go clear if they beat Novara today, and are still unbeaten.“We have to look at the long-term objectives and bring home three points every time, otherwise in a few months we could feel the weight of those dropped points.”
