Kai Havertz and Christian Pulišić were on target as Chelsea overcame LOSC 2-0 in this UEFA Champions League round of 16 first leg.
Chelsea took control of their Champions League last-16 tie against Lille with a comfortable victory at Stamford Bridge.
Fresh from winning the FIFA Club World Cup a week ago, Chelsea started authoritatively and Kai Havertz could have had a hat-trick inside eight minutes. The German striker, who fired his first chance over then was denied by Leo Jardim, took his third opportunity with a downward header from Hakim Ziyech’s corner.
Jardim then saved from Marcos Alonso before the visitors established a foothold in the game, though they only had Edouard Mendy’s save from Benjamin André’s 36th-minute effort to show for their improvement before the break.
Thomas Tuchel’s men wrested control back after the interval and Zeki Çelik block’s from Alonso could only temporarily stem the tide. The second goal finally arrived in the 63rd minute thanks to a wonderful driving run through the centre from N’Golo Kanté, who then slipped in Christian Pulišić to place his finish inside the far post.
LOSC avoided further damage but Jocelyn Gourvennec will know his side will need to show more potency up front if they are to have any hope of turning the tide in the return on 16 March.
The only negatives on a good night for Chelsea and manager Thomas Tuchel were injuries to Ziyech and midfielder Mateo Kovacic ahead of Sunday’s EFL Cup final against Liverpool at Wembley.
