Shortly after scoring his first Premier League goal for Chelsea, midfielder Tiemoue Bakayoko vowed there and then to celebrate by dyeing his hair blue.
"As soon as I score a goal I will change the colour of my hair. Possibly to blue," he said. "I like changing the colour of my hair from time to time."
Sure enough, just three weeks after Bakayoko netted in the Blues' 2-1 defeat against Crystal Palace in mid-October, the France international has debuted his daring new 'do.
Hardly a huge departure from the brilliant white style he previously sported, but a shocking splash of colour nonetheless!
