Mercedes changed their engine 3 or 4 races ago and have won every race since. It made them faster than red bull.
Christian Horner has just said the guy who changed the circuit has improved every part for Mercedes.
He said its David and Goliath .
I get he could be trying to play a fast one.
I had a few quid on Mercedes for constructors championship and Hamilton to win the championship double 3 or 4 races ago
Barring a disaster I am confident that bet will come in...
