He impressed me for the first time today. Conte's tactics today were very Roma-esque circa 2008 when Totti was the lone front man due to an injury crisis and they had like four midfielders pouring forward. It was cool to see.
As long as someone is contributing up front to assist the lone striker like Marchisio did against Parma and Milan or Lichtsteiner did in the Parma match also. I don't know if they took it upon themselves to do it or its a tactic of Conte's but its very useful and unpredictable giving defenses one more attacker to unexpectedly mark.
