Stoke City forward Saido Berahino says that he has lost a considerable amount of weight since he joined the Potters in January.

The £15m-signing from West Brom struggled with his fitness during his time with the Baggies.

"I've lost about six kilograms, six or seven," Berahino said.

"It's been very easy for me to shift that weight. The way my body is, when I'm playing, I trim down. When I'm not playing, I put on weight. I've got to blame my family for the genes they gave me."

"It's just that I put on weight easily if I don't move. If I don't do exercise, my weight just goes up. That's what happened at West Brom."
