#4 Vettel Pulls the Championship Lead back
While Lewis Hamilton may have won the race in Baku and subsequently taken the lead in the race for a 5th World Championship, Vettel is certainly not out of it. Only 4 points separate the pair of 4 time World Champions and Vettel is in blistering form.
With only a single mistake costing him the win in Baku, and with Hamilton essentially inheriting the win from Bottas, Raikkonen and Vettel himself, the momentum sits squarely with the German.
Lewis Hamilton himself has admitted, in concurrence with Nico Rosberg and others that when he loses the momentum in a Championship race, he tends to take a while to get it back.
His victory in Baku should, therefore, be seen as one of circumstance rather than signs of Mercedes making drastic improvements to their car, and Hamilton to his driving.
Spain doesn't promise chaos like Baku, and if Vettel is as flawless as he usually is, then he should be able to finish ahead of his Mercedes rivals and bring the Championship lead back to the Tifosi.
