Former F1 boss Bernie Ecclestone believes Lewis Hamilton is "fed up" with Formula One and as a result is "not the racer he was" in the past.
Reigning world champion Hamilton is still yet to win a race in 2018 and found himself out of form at the Chinese Grand Prix, where he finished behind teammate Valtteri Bottas in qualifying and the race. Although Hamilton confessed he's not felt 100 percent with the car yet this season he came to Baku, host of this weekend's Azerbaijan Grand Prix, confident of a quick fix.
Ecclestone, who was removed from power at the start of 2017, says he has noticed a change in Hamilton's demeanour in recent months.
