Mediocre first half by Juve, Del Neri needs to shake things up a bit. Aquilani is needed. Maybe instead of Melo, the problem is Melo's defensive game has been quite good, he hasn't let Sampdoria's midfielders be comfortable on the ball, he's continuously hassling them and covering a lot of ground, but he's giving away possession too much.
DP has shown some magic touches here and there, i don't think he's done that badly, only problem is, he gets anonymous for extended periods of time during the game, but still he can come up with something every now and then, like he did in the goal.
