Willian's wonderful late volley handed Frank Lampard his first Champions League victory as a manager as Chelsea beat Lille 2-1 on Wednesday
Birthday boy Tammy Abraham's eighth goal of the season handed Chelsea the lead midway through the first half, but 20-year-old Victor Osimhen drew Lille level before the break with his seventh goal for the Ligue 1 club
Kepa Arrizabalaga bailed Chelsea out with a string of saves in the second period as Lille pushed for a winner in front of an expectant home crowd
But the night belonged to Chelsea as Willian marked his 300th appearance for the club with a stunning volley from Callum Hudson-Odoi's cross to get Lampard's side off the mark in Champions League Group H
Frank Lampard handed 19-year-old Reece James his Champions League debut in a youthful Chelsea side that made an encouraging start in the hostile surroundings of the Stade Pierre-Mauroy, where the closed roof ramped up the atmosphere
Mason Mount had the Blues' first opportunity, bringing a clearance under control on the edge of the area on 17 minutes, but his finish left much to be desired as he volleyed well wide of the target
But Lampard's faith in youth was rewarded soon after thanks to a birthday goal from Abraham, gift-wrapped by his academy team-mate Fikayo Tomori, as a defence-splitting pass found the 22-year-old in space in the box, and he controlled, swivelled and fired into the far corner
Chelsea's inexperience at Champions League level saw them lose control of the game, and their lead lasted just 11 minutes as Lille dangerman Osimhen was given the freedom of the penalty box to head his seventh goal of the season beyond Kepa
But Chelsea managed to wrestle back the initiative and were unfortunate not to restore their lead before the break as Jorginho's first-time curler from James' cutback rattled the frame of the Lille goal in the final minute of the first period
With the game there for the taking, both sides readily exchanged blows after the break
 Tomori headed a Willian corner over within four minutes of the restart before Benjamin Andre's glancing near-post header from a corner drew a fine fingertip save from Kepa
After Lampard introduced Hudson-Odoi, Osimhen spurned a glorious chance to double his and Lille's tally when he selfishly went alone after being played into space down the right channel and blazed over at the near post instead of squaring for a team-mate in space
And he was made to pay the price 13 minutes from time as Hudson-Odoi's brilliant cross from the left fell perfectly for Willian, who volleyed a shot into the turf and over Mike Maignan in the Lille goal to seal Lampard's landmark victory
Chelsea manager : "To be on zero points after one game is one thing but to come away tonight against a tough team, knowing that every game is going to be tough, it gives us confidence, it gives us points, it gives us a feeling in the group we're in a better position
 Now the hard work begins in this group because every game is going to bereally tough
"With Gareth Southgate set to name his squad for England's Euro 2020 qualifiers against the Czech Republic and Bulgaria on Thursday, Tammy Abraham picked the perfect time to score his first Champions League goal and remind the national team boss of his fine finishing ability
Abraham hasn't featured for England since playing in friendlies against Germany and Brazil in 2017 and is also eligible for Nigeria
 An appearance in either of England's upcoming qualifiers would end that uncertainty and the 22-year-old's form warrants an opportunity
The striker has seven Premier League goals already this season, including a hat-trick at Wolves, and his smart control and clinical finish against Lille underlined the danger he poses in the opposition's box
 With Marcus Rashford out of sorts and reportedly struggling with injury, now could be an ideal opportunity for Southgate to make room in his squad and give Abraham his shot
