FRANKFURT, Germany: England fans were left perplexed by video of defender Kieran Trippier drinking pickle juice during Sunday's 1-0 win over Serbia, but Kyle Walker said ingesting the juice was nothing new.
"I think it's been around for quite a while," the England defender said on Wednesday. "It's just been highlighted when Tripps had the picture."
Pickle juice is believed to help prevent cramps, and while science has yet to prove its effectiveness, it is widely used by athletes, such as ultra runners and tennis players.
Spain's Carlos Alcaraz was spotted drinking it during his victory over Novak Djokovic at Wimbledon last summer.
"I don't take it, personally. I keep myself well-hydrated," Walker said. "I've been very fortunate not to receive the cramps or anything.
"It's part and parcel of football now. Football is developing and that's something sports science think can benefit us at the late stage of the game."
Midfielder Kobbie Mainoo appeared surprised when he was asked about it.
"I've not tried pickle juice," the 19-year-old said. "I didn't know that was a cramp fix. I'm not doing it!"
