Story of the match
The tie got off to a bright-start for the newly crowned Champions of the World, who donned the famous gold badge after beating Palmeiras in the FIFA Club World Cup final in Abu Dhabi just under a fortnight ago.
The man for the big occasion, Kai Havertz headed home in the seventh minute, with the French side already given scares earlier on after the German missed two opportunities before making it count.
After an early goal though, Jocelyn Gourvennec’s side sustained large amounts of pressure, although the Ligue 1 side failed to create any real opportunity.
Renato Sanches’ cross-shot went close after Antonio Rudiger’s attempted clearance sliced just over the bar.
Portuguese international Sanches was heavily involved for Lille, with the midfielder almost certain to attract interest from clubs across Europe after it was reported earlier this week that the 24-year-old had refused to pen a new deal.
The second-half got off to an end-to-end start, although both teams failed to capitalise on any real chances.
That changed on 63 minutes, when N’Golo Kante’s run followed a short through ball to American international Christian Pulisic, who’s scuffed dink gave the hosts a two-goal advantage.
Post match, Tuchel said: “I should have substituted Kovacic at half-time so we could have saved one more change. I have not spoken to the doctor yet with Hakim [Ziyech]. I hope it is not too much.”
