Pedro scored an away goal as Chelsea recovered from an early setback against Eintracht Frankfurt to set up an exciting Europa League semi-final return leg at Stamford Bridge.
Eintracht took the lead in the 23rd minute through their top scorer Luka Jovic, who superbly steered in Filip Kostic‘s ball.
The goal was the 21-year-old’s ninth of the competition and 26th this season but Frankfurt failed to press home their advantage, running out of energy in a second half dominated by the visitors.
The Blues, who started with Eden Hazard on the bench, equalised when Pedro thrashed home just before half-time.
Chelsea were far livelier after the break, in a reversal of the first 40 minutes, with the hosts having a close escape when David Luiz rattled the crossbar from a 55th minute free kick.
Chelsea manager Maurizio Sarri left Hazard on the bench until the 62nd minute, preferring to rest the Belgian forward for the important Premier League games against Watford and Leicester City.
The draw means that Chelsea become the first team to go 16 successive Europa League matches without defeat, breaking the record set by Atletico Madrid from 2011 to 2012.
They will have the chance to make it 17 in next Thursday’s second leg.
