In an era of ?50m strikers, Hernandez is real value for money, a top bit of business by Sir Alex Ferguson. That's why I hailed him as one of the best buys of the century while covering United's Champions League quarter-final win over Chelsea for Sky Sports.
He scores goals and bosses will pay top whack for players who do that. Sir Alex didn't have to.
Easy Peasy: Javier Hernandez scores against Chelsea
JAMIE'S TOP THREE JAVIER HERNANDEZ
?6m Guadalajara to Man Utd, 2010
?1.7m Millwall to Everton, 2004
I love players coming from the lower leagues and making a success of themselves. Just look at Everton when he doesn't play - he is sorely missed.
?5m (and rising) Southampton to Spurs, 2007
His potential is boundless. He's amodern-day athlete, who just getsbetter and better. I've seen itfirst-hand working in the ChampionsLeague this season: everyone inEurope is talking about him.
Hernandez isn't a kid, either. Yes, he's 22, but he's a tried and tested striker with international pedigree. He played at the World Cup where he featured in every game for Mexico and scored twice - against France and Argentina. Signing him was not much of a gamble.
He looks like the sort of player who will go on to be a success for many seasons at Old Trafford because he has a love of the game.
People talk about secondseason syndrome, but his movement has convinced me of his quality. He reminds me of Robbie Fowler but quicker. He plays on the edge, hanging on the shoulder of the last defender. He makes it difficult for opponents and assistant referees - as we saw twice against Chelsea.
I also think Tim Cahill and Gareth Bale have been brilliant buys since 2000. So they're both in my top three.
And here's what sportsmail's other experts think.
MARTIN KEOWNCRISTIANO RONALDO
?12m Sporting Lisbon to Man Utd, 2003
Delivered trophies. At times unplayable, strutting down the wing and terrorising defences. His legacy is more than the money he was sold for.
?7m Rennes to Chelsea, 2004
An absolute snip at ?7m and an inspired signing. Chelsea have had one of the best - if not the best - goalkeeper in the Premier League for the last five years.
?700,000 Barca to Arsenal, 2003
So cheap for what Arsenal got. He is superb to watch.
People talk about Steven Gerrard at Liverpool but Fabregas is the same at the Emirates: when he is in the team, Arsenal invariably win; when he's not, they struggle.
MATT LAWTON CRISTIANO RONALDO
For ?12m United bought a prodigy who became a superstar. His 42-goal season has gone down in lore. United made ?68m profit but got two Champions League finals out of him first. PETR CECH
Arsene Wenger should read this: Cech's the keeper in front of which title-winning teams were built. Just ?7m bought eight major trophies. Solid, dependable, world class. XABI ALONSO
?10m R Sociedad to Liverpool, 2004
Bought for ?10m, sold for ?30m, having helped Liverpool win the Champions League, reach a second final and lift the FA Cup. His calm and effective passing was the perfect foil for Steven Gerrard to turn in match-winning performances.
ANDY TOWNSEND KOLO TOURE
?150,000 ASEC Mimosas to Arsenal, 2002
An absolute warrior who formed a worldclass partnership with Sol Campbell. They sold him for ?16m, which turned out to be fantastic business.
?600,000 Shrewsbury to Man City, 2006
City bought an England keeper for peanuts. He played 50 games in League Two before he had turned 18. His displays ooze confidence and he will only get better.
?11m West Ham to Chelsea, 2001
Their most consistent performer in the Abramovich era - even if this season hasn't been his finest. Has played more than 500 games at around 50 a season and Chelsea never looked to make a profit as his performances were priceless.
DES KELLYNEMANJA VIDIC
?7m Sp Moscow to Man Utd, 2006
The natural heir to Stam. Remarkable value if you consider you can buy three and a half Vidics for one Joleon Lescott.
Now the finished article - and will be worth 50 times that original steal fee if the Catalans wish to bring his story full circle.
EDWIN VAN DER SAR
?2m Fulham to Man Utd, 2005
No wonder Ferguson wants to extend his career. He's the best since Schmeichel.
MICHAEL WALKERFRANK LAMPARD
Has been a priceless contributor to Chelsea's best-ever decade.
?5.5m Monaco to Man Utd, 2006
He adjusted quickly to the rhythm of United's football and to English physicality.
?275,000 Peterborough to Wigan, 2003
Wigan were in the third tier when Bullard signed. By October 2006 Wigan were second in the top flight. He then helped establish them as the most unlikely PL club.
MATT BARLOWFRANK LAMPARD
Has played 502 games and scored 166 goals. That's less than ?60,000 a goal.
He was both brilliantly entertaining and ruthlessly clinical, although a bit of a supercilious winker at times.
?0 Southampton to Bolton, 2003
Most were ready to file him away as a flop, but has barely missed a game in eight seasons since.
Not prolific, but leads the line selflessly and now a dignified captain.
DOMINIC KINGTIM CAHILL
Averages a goal from midfield every four games. Moyes rightly rates this as his best piece of business.
?0 PSG to Bolton, 2002
Lit up the Premier League with his repertoire of tricks. Captained Bolton to the 2004 League Cup final and ensured they kept their place in the top flight.
?6m Villarreal to Liverpool, 2005
The fact his statistics are better than those of legend Ray Clemence says everything.
