[6] Angel Bleu made his debut in a novice race (for horses with no more than two previous wins) over five furlongs at Leicester Racecourse on 9 April when he started at odds of 11/4 and finished third behind Gubbass, beaten five lengths by the winner.

Sixteen days later the colt was ridden by Hector Crouch when he started favourite for a novice race over the same distance at Salisbury Racecourse and recorded his first success as he took the lead approaching the final furlong and won by one and three quarter lengths from Raging.

[7] Angel Bleu followed up in a minor race over six furlongs on soft ground at Pontefract Racecourse on 28 May winning from Khunan and Lusail after taking the lead in the closing stages.

[10] On 2 October Angel Bleu was sent to France and started at odds of 5.5/1 in a nine-runner field for the Group 1 Prix Jean-Luc Lagardère over 1400 metres on heavy ground at Longchamp Racecourse.

"[12] Twenty days after his win at Longchamp, Angel Bleu returned to Frane to contest the Group 1 Critérium International over 1600 metres at Saint-Cloud Racecourse.

After racing at the rear of the field in the early stages, he overtook the front-running outsider Toimy Son 200 metres from the finish and repelled a late challenge from Ancient Rome to win by a head.
