William Gallas and Didier Drogba won back-to-back league titles with Chelsea before the defender left for Arsenal in 2006.
Gallas has admitted he only understood Drogba’s power when he played against him.
“I was used to seeing him in training, but you know how it goes: you’re never going at 100 per cent on the training pitch,” Gallas told The Athletic.
“So I never really understood why [Philippe] Senderos would just go missing in every match he played against Didier. But when I played against him myself in the Premier League with Arsenal, then I understood.
“He had something about him, a power I’d never sensed as a team-mate, an aura I had never seen before. Facing that, you just shit yourself. He was so intimidating that it rattles you.”
