Chelsea boss Maurizio Sarri has expressed his admiration for Eintracht Frankfurt striker Luka Jovic.
The two teams will meet in the Europa League semifinals with Jovic, who is a target for several European heavyweights, to lead the line for the Germans.
Chelsea have been linked with Jovic and Sarri said after victory over Slavia Prague: "We did very well in the first half and of course we are really happy to reach a European semi-final because we know that is not easy.
"To reach the final would be great for us but we need to study Eintracht Frankfurt very carefully now because they are a great team with a wonderful striker in Luka Jovic."
