'We have to wait': Barca's Flick on Lewandowski injury fear

Barcelona are waiting to find out if striker Robert Lewandowski will be fit for the Copa del Rey final and the Champions League semi-final after he appeared to suffer a hamstring injury on Saturday.

The Polish forward, 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.

Barca face Mallorca on Tuesday in LaLiga and then Real Madrid in the Copa final on April 26, before hosting Inter Milan in the Champions League semi-finals on April 30.

"We have to wait... from my experience we wait until tomorrow," said Barcelona coach Hansi Flick, whose 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.
