Lewis Hamilton primed for toughest challenge in Monoco
Formula one: Lewis Hamilton believes he faces the toughest title battle of his Formula One career in squaring up to Mercedes team-mate Nico Rosberg this season.
Hamilton heads into this weekend's Monaco Grand Prix at the top of his game after a run of four successive victories.
Despite such domination, Hamilton only has a three-point cushion to Rosberg.
And with his main rival for the crown in the opposing garage and with the duo sharing data, it means there is little opportunity to gain an advantage.
Hamilton said: "This is the toughest title fight, definitely.
"It's the same for Nico because I see his data, which makes it so hard for either of us.
"It would almost make sense to copy his set up. You could if you wanted to and then it would just depend on ability. But I'm pretty sure we'll keep sharing data. That's how it works."
