Continuing my week of drawing from the ATP World Tour Finals at London’s O2 Arena is the young Austrian tennis star and world No.4 Dominic Thiem who faces David Goffin today in a sudden death match to decide who goes through to the semi-finals. This is the second consecutive year that Dominic has reached the Tour Finals, having made the semi final at Roland Garros and the fourth round of the three other Grand Slams. Winner of eight ATP singles titles, he is known for his aggressive base line play and great defence and is one of the few younger players to use a single-handed backhand.

He signed my sketch last Sunday at the O2.
