I think this needs a more level-headed approach (and yes, given time I’ll do the same for all races, all 3 top cars).
Malaysian Grand Prix
Race pace:
Is there reason to believe Vettel and Hamilton could not have matched Alonso’s race pace in his Ferrari considering …both Vettel and Hamilton’s ‘clean air’ times were about as much faster to their team-mates as Alonso’s was to Massa. (FL not representative comparison in wet)
Is there reason to believe Vettel and Hamilton could not have…
…overtaken Nico Rosberg in lap 1 (Schumacher and Grosjean clashed) from p8 to p5.
…overtaken Mark Webber for p4.
…leapfrogged Button and Hamilton in the pits for p2.
…overtaken Sergio Perez for p1 and defend against him for the 3 laps he was within 2 seconds.
European Grand Prix
Race pace:
Is there reason to believe Vettel and Hamilton could not have matched Alonso’s race pace in his Ferrari considering…
…Alonso’s fastest lap was 0.765s faster than his team-mate’s.
…Hamilton fastest lap was 0.799s faster than his team-mate’s.
…Vettel was flying today (FL not representative considering DNF).
On track performance:
Is there reason to believe Vettel and Hamilton could not have…
…jumped from p11 to p8 in lap 1 (Massa moved from p13 to p10, also past Rosberg and Button).
…overtaken Hülkenberg and Maldonado on soft tires, with those two on medium.
…overtaken Webber, Senna, Schumacher and di Resta on old tires for p4.
…overtaken Hamilton in the pits for p3 when McLaren screwed up the pit stop.
…overtaken Grosjean on the restart (not too unsimilair to Vettel’s move on Rosberg in Australia; I have little doubt Lewis could not make that move).
…picked up the win when the race leader’s alternator failed.
German Grand Prix
Is there reason to believe Vettel and Hamilton could not have matched Alonso’s race pace in his Ferrari considering…
…Alonso’s fastest lap was 0.181s faster than his team-mate’s.
…Vettel’s fastest lap was 0.325s faster than his team-mate’s.
…Hamilton brawled with Alonso and Vettel (FL not representative considering DNF).
On track performance:
Is there reason to believe Vettel and Hamilton could not have…
…taken pole position on much fresher tires.
…lead the race from the front (Massa’s free air pace was not too dissimilar).
Now, as I have said very often, Fernando Alonso is a great driver, who drove some great races, but there is no reason to Sebastian Vettel or Lewis Hamilton could not have won those races in those circumstances.
If you believe there is, please point to where Alonso put in a performance the other two great drivers on the great would not have been able to.
