Will be disappointed not to have held Icardi's opener, which wriggled under his body. Followed that faux pas by being beaten at the near post for the second.
Was combative and busy in defence at first and did not look overwhelmed by the famous shirt, until he was twice caught out on the left side to devastating effect. Not the debut he would have been dreaming of.
The pick of the Turin side's defence, played almost as a holding midfielder and was always there to get the attack moving again.

Put in countless crosses of varying quality over the course of the match, but could not make the difference and was sacrificed as Juve chased victory.
Was decent enough for the vast majority of the encounter, but had no answer to Sampdoria's counters that turned the game around after the break.
Was punished severely for losing possession in the build-up to the equaliser. A muted display, typified by countless corners that failed to reach their target.
Consistently reached the bye-line and troubled the Samp defence with his crossing. However, there was ultimately no end product and the game passed him by for long periods.
The urgency and drive he usually gives the Juve midfield was oddly absent, as the Frenchman ended up simply going through the motions.
A storming run earned Juve their penalty and only strike of the game. Left the field in agony after landing heavily and would be a big absence for the Serie A holders.
Was rather unlucky not to win a second penalty after slipping past Sampdoria's last man. Again though, an uneven performance from the attacker, who is running out of chances to salvage his Juve career.
Took his penalty with class, and was a constant headache for a Sampdoria defence that struggled to contain the mobile young forward.
A heroic performance from the Argentina No. 1, produced save after save to frustrate the hosts and could only be beaten from the penalty spot.
A real captain's performance from the right back, marshalled his defence perfectly at set-pieces and ensured that Romero would be covered.
The villain of Sampdoria's underwhelming first 45 minutes. Gave away a needless penalty, and followed that up with a nasty challenge on Barzagli that earned a second yellow.
Along with Palombo, refused to give in despite being constantly under the hammer as Juve streamed forward. Made some crucial interventions.
Was one of Sampdoria's brightest players in a disappointing first-half, before an early knock forced him off at half time.
Massive display from the centre-back, who never folded under immense pressure and who was a titan in the air.
Dispossessed Pirlo in midfield and released a stunning cross-field pass to play in Icardi for the equaliser. Never stopped working.
Had few chances to shine, but was a constant presence in midfield and caused Juventus problems on the few occasions he ventured forward.
Made one telling contribution with a neat pass to Iscardi on the right hand side, which led to the striker's second goal and his team's winner.
Was happy to drop deep and look for the ball against an attack-minded Juve, and was the mastermind of more than one of the away team's excellent counter attacks.
An unforgettable day for the striker. Took his chances fantastically with two top-class finishes, to upset Juventus and turn the game round.
