Against the South American nation, 'SuperVan's' powers appeared to have completely deserted him. The 30-year-old failed to register a shot against Argentina... his decline in form will have United fans wondering whether Van Gaal can bring out the best in his compatriot when he takes over at Old Trafford.
In a world saturated by political correctness, absolutely everything can be perceived as 'offensive', 'inappropriate' or 'unsafe' if people deliberately choose to see things in a certain way. Most acts of celebration in football remain perfectly innocent, whilst others are just subject to unreasonable rules...
The arrival of Mata in the North West will certainly remove some of the burden from the young winger - and it is a clear rallying call and statement of intent from the Manchester United board. They might be down, but they're certainly not out. Yet.
Why is a man who decides so many crucial games so rarely on the team sheet? There is one obvious answer, coming in the form of two iconic names: Wayne Rooney and Robin van Persie. The duo have dovetailed superbly this season, netting 17 times between them and assuaging Moyes' difficult start to his reign.
If Rooney doesn't stake his claim for a starting berth further forward it wouldn't be outlandish to suggest that now is the time, for him as much as the team, given his age and subsequent value to continue the process of finding himself in different colours.
If Suarez doesn't win the award, as seems likely, it is because he is a villain of Iago-esque proportions, the bête noire of the Premier League. He's not just the player who everyone loves to hate, he genuinely is hated.
Another striker is imperative. With Adebayor away, Defoe is effectively the only senior forward at the club and an injury to him would be nothing short of disastrous. Furthermore, over the last few weeks Defoe and Adebayor have shown that they struggle to score when playing together, so even when they are both available options are sparse.
Who knows what butterfly effect would have occurred had Koscielny and Szczesny not had that last minute moment to forget? Wenger will definitely have nightmares thinking about that as the 2010/2011 season was Arsenal's best chance of ending their trophy drought.
As Wenger's changed and Arsenal have become less competitive, I've warmed to him but also, unashamedly, become a critic of what he's done and what he's trying to do.
The nauseating bone-deep gash to his thigh was not the only thing that would have had Wayne Rooney grimacing on Saturday last.
The main event of Sky Sports' Super Sunday was a contest between two teams trying to adapt to new systems, with somewhat mixed results.
When 'Le Professeur' first joined Arsenal he revolutionised the Premiership with 'The Arsenal Way' and the principles that accompanied this policy. His fitness regimes extended the careers of the 'old guard' of the Arsenal back four, and his training methods re-sculpted and brought the best out of players like Bergkamp and Henry. His scouting network unearthed young talent from across the world, and his tactics delivered success in sublime style.
Amid Robin van Persie's transfer from Arsenal to Man Utd and Luka Modric's imminent move away from Spurs to Real Madrid, questions are again to be raised over what exactly motivates footballers and the choices they make.
Robin van Persie is Manchester United's first marquee signing since Dimitar Berbatov in 2008, but can the marquee buy make his mark amidst an overload of attackers at Old Trafford?
Arsenal's performance in the 2003-4 season saw them dubbed 'The Invincibles' after going an entire Premier League season without a loss, a feat yet to be repeated. Fast forward to 2012 and Arsenal now teeter on the edge of losing their third marquee player in two years.
The Robin van Persie ride is coming to an end, but Arsenal's rollercoaster looks set to go on for days, weeks, months, and maybe years to come.
