Lionel Messi returned to training with Barcelona on Thursday after receiving treatment for kidney stones which affected his participation in December’s Club World Cup.
The Argentine superstar had tests “to assess the development of kidney stones,” Barca reported.
Messi missed Wednesday’s 1-1 Copa del Rey semifinal second-leg draw with Valencia, with the Catalan side prevailing 8-1 on aggregate.
The five-time World Player of the Year is due to start Sunday’s Liga clash with Celta Vigo at the Camp Nou where he needs only two goals to become the first player in the Spanish league to score 300 goals.
“With the renewed presence of Leo Messi in training Barca is already focussing on the next Liga outing,” the club said.
Messi suffered renal colic, a problem commonly caused by kidney stones, in Japan in December forcing him to miss eventual winners Barcelona’s semifinal against China’s Guangzhou Evergrande.
He recovered in time to line up in the final where Barca beat Argentina’s River Plate 3-0 as he scored the opening goal.
