Barcelona's Polish forward Robert Lewandowski went off hurt against Celta Vigo on Saturday

Barcelona (AFP) - 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 La Liga 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.
