During both the warm-up and the match itself, the 20-year-old midfielder had both legs covered in some rather colourful taping.
Is this the latest fashion accessory for footballers - or is there another reason behind it? Turns out, thankfully, that it’s the latter.

Alli also wore the same patterned leg tape against Everton last season, and The Sun have now discovered the reason behind it.
Apparently, the material is part of the Kinesio Taping Method, whatever that means.
One expert, according to The Sun, has described the technique as: “A definitive rehabilitative taping technique that is designed to facilitate the body’s natural healing process while providing support and stability to muscles and joints without restricting the body’s range of motion.
“It also provides extended soft tissue manipulation to prolong the benefits of manual therapy administered within the clinical setting.
“Latex-free and wearable for days at a time, Kinesio Tex Tape is safe for populations ranging from pediatric to geriatric, and successfully treats a variety of orthopedic, neuromuscular, neurological and other medical conditions.
“The Kinesio Taping Method is a therapeutic taping technique not only offering your patient the support they are looking for, but also rehabilitating the affected condition as well.
“By targeting different receptors within the somatosensory system, Kinesio Tex Tape alleviates pain and facilitates lymphatic drainage by microscopically lifting the skin.
"This lifting affect forms convolutions in the skin thus increasing interstitial space and allowing for a decrease in inflammation of the affected areas."
Dele Alli wasn't at his best against Liverpool
That solves that little mystery, then.
Unfortunately, though, the taping on Alli’s legs didn’t help him in terms of performance against Jurgen Klopp’s men.
The England international looked off the pace at times and still appears to be a little short of full fitness following his involvement with England at Euro 2016 earlier this summer.
Alli was also wearing ‘Dele’ on the back of his shirt, instead of his surname, and you can discover the reason why by clicking HERE.
