People recognize that Messi's transcedescence rests not in the highlight-reel goals and never-ending statistical dominance, but in his ability to do something smart, productive and often awesome every time he's on the ball.
It all started with the five-time Ballon d'Or victor scoring an absolute peach of a free-kick from outside of the box - it was out of this world - but the Argentine seems to have his Barcelona teammates preparing their celebrations before he's even hit the back of the net.
Against PSV, Messi managed to overtake the Juventus forward in terms of hat-tricks scored in the major European competition.
"Barcelona fight for all the competitions but the Champions League is the biggest and we are going to go for it".
With his hat trick on Tuesday, he now leads Ronaldo 63-60 in total group-stage goals.
Van Bommel also lauded five-time world player of the year Messi, saying: "For me he is the best player in the world".

While Messi once again stole the headlines, there was another impressive performance from Dembele, who scored his fifth goal of the season after spinning two defenders and curling home from 25 yards.More news: Union Cabinet approves ordinance on triple talaq, makes it a punishable offence

PSG had come back from two goals down with Kylian Mbappe equalising in the 83rd minute after Thomas Meunier's 40th minute strike halved the deficit. Firmino collected a pass from Virgil van Dijk and fired a low shot into the far corner to seal the Reds' victory.
The Dutch team is the 30th different club that the Argentine has scored against, since his debut goal against Panathinaikos in 2005.
They have failed to get beyond the quarterfinals for the last three seasons while arch rivals Real Madrid have won club soccer's most coveted prize three years in a row.
The France worldwide struggled for the club after signing from Borussia Dortmund a year ago. "To come off the bench after his injury at the weekend is incredible really", said Klopp of Firmino, who was poked in the eye by Jan Vertonghen in the weekend win at Spurs.
They had three good chances to take the lead and Hirving Lozano might have equalised in the second half too, had Gerard Pique not made a scrambling last-ditch block.
Barca were off the pace for much of the first half of Tuesday's Group B clash, but Messi broke the deadlock with a trademark free-kick.
Diego Costa equalised for visitors on 31 minutes before defender Jose Gimenez headed home the victor from a corner on the stroke of halftime. Many supporters could not get to the games in MIlan or Barcelona in time after work and were forced to miss out because of these changes.
