Flick insists Barca 'have to wait' to assess Lewandowski injury

Robert Lewandowski, Barca's top scorer this season, was taken off in the final stages of his team's 4-3 win against Celta Vigo, which put the Catalans seven points clear of second-placed Real Madrid.

Barcelona face Mallorca on Tuesday in La Liga and then Real Madrid in the Copa de Rey final on April 26, before facing Inter Milan in the Champions League semi-finals on April 30 and May 6.

"We have to wait... from my experience, we wait until tomorrow," said Barcelona coach Hansi Flick on the Poland striker, as his side are chasing a potential quadruple of trophies.

Spanish media reported Lewandowski could be out for three weeks, which would put him at risk of missing both legs of the Champions League semi-final. Spaniard Ferran Torres is set to take Lewandowski's role in the attack if the 36-year-old is sidelined.
