Valverde: Rest assured with Messi, he has a lot of energy left for the World Cup LaLiga - Celta vs Barcelona Txingurri will rotate at Balaidos

Ahead of Barcelona's match at Celta Vigo, Ernesto Valverde dropped the biggest hint yet that he will rotate his squad, but also noted that, despite a niggling injury, Lionel Messi has still got enough in the tank to see him through this season and the World Cup in the summer.

It's been three years without a win at the Estadio Balaidos for the Catalans, and with the Copa de Rey final on the horizon, it appears Valverde is throwing his eggs into that particular basket.

"It's a possibility that Messi rests, like others," he said at his pre-match press conference.

"There's nothing to worry about, the other day he played a good game, and they're calm in Argentina because Messi still has a lot of energy left for the World Cup."

Having a less than full-strength squad could play right into Celta's hands, and might also deprive Barcelona of going the entire season unbeaten.

"We come from intense matches and on Tuesday we will have to make some changes to refresh the team," he continued.

"We have already faced them three times this year, they are having a good season and fighting for Europe.

"For us it is an encouragement to fight for these three points, but it will be a difficult match."

A lot has been said about a possible exit for Andres Iniesta, but Valverde didn't want to dwell on the issue.

"It has not happened yet," he added.

"There have already been other players that have left and life goes on.

"So far it has not been announced and we are not going to speculate on this issue."
