10. Timo Glock
He looked good as Jordan's Friday driver in 2004, usually quicker than Giorgio Pantano. When he stood in for the Italian in a race, he scored a point. Fast-forward four years and, with Champ Car and GP2 experience, he was instantly able to operate at a good F1 level with excellent overtaking and general race judgement.
Initially, he was over-awed by Jarno Trulli finding tyre temperature for a qualifying lap and those vital two or three extra tenths, leaving Timo two or three rows behind - something that tends to define your race.
He's more of an oversteer driver than Trulli, so the TF108's reluctance to find instant front-tyre temperature didn't suit him. He applied himself impressively to the task though and, in the second half of the year, consistently challenged Trulli. He was running particularly well at Hockenheim until a major suspension-induced shunt. That he came back to finish second in the very next race was impressive.
