The first time Claudio Marchisio left an impression on me was a few years ago against Cesare Prandelli's Fiorentina.
At the time, the Viola's No. 88, Felipe Melo  was one of the league's best players. There was also Riccardo Montolivo pulling the strings.
Yet, it was a then 23-year-old Marchisio who outperformed both players with his energy. He also ended up scoring what turned out to be the only goal of the game.
Alessandro Del Piero had the attention of five Fiorentina players.
Marchisio took note, made a smart run on the blind side of Per Krøldrup and received an immaculate through ball from Il Pinturicchio. From there, Marchisio slotted the ball past Sébastien Frey from an acute angle.
In a 2-1 win over José Mourinho's Inter Milan, Marchisio showed he was a fighter.
With possession on the left flank, he fended off Walter Samuel and launched a diagonal ball to Mohamed Sissoko, who shot from distance.
Júlio César parried the shot, Samuel thought he could win the ball but Marchisio got to it first, danced his way past the Argentine before he dinked the ball over César.
Last season, Marchisio stole the limelight with two goals in the last eight minutes against AC Milan.
These examples, and there are plenty more that I haven't talked about, show that he plays big when the game is on the line.
It's slightly ironic because he used to receive criticism for shrinking under the bright lights.
This season, he's proving that he is the man for the moment once again.
In a 2-2 draw against UEFA Champions League champions Chelsea, Marchisio orchestrated a comeback from a 2-0 deficit after Oscar's unforgettable two-minute brace.
The Italian provided two assists, completed 95 percent of his passes and won back possession six times.
Several weeks ago, when Siena were holding on for dear life at 1-1, with five minutes to go, who stepped up to score the winner?
Of course it was Marchisio.
 Five months later, Juve signed Melo for €20.5 million plus Marco Marchionni.
