Chelsea boss Maurizio Sarri admits he's a fan of Eintracht Frankfurt's strikers.

Chelsea host Eintracht Frankfurt for the second-leg of their Europa League semifinal with the aggregate score locked at 1-1.

"It's not easy because we have to play a dangerous team, as we saw in the first leg," said Sarri.

"They are dynamic, aggressive and dangerous in the offensive phase, especially when they find space in counter-attacks, so it's a dangerous match.

"In a semi-final, you always have to play against a strong team with strong players so it's difficult to say we are favourites. They have two good strikers in [Luka] Jovic and [Ante] Rebic so we have to be careful."
