I didn't expect Real Madrid defeat by Lille a League 1 club, even though Lille is not a strong enough club for Madrid and of course many people don't believe that Madrid could experience a defeat like this.
Lille made it difficult for Madrid even though Madrid tried to make many shots but none of them were successful. Lille really kept their defense tight and they were lucky to get a penalty so they could excel over Madrid and win.
Madrid was indeed more favored in the match, but Lille played very well. Madrid did not press Lille's game completely. and that resulted in Lille's game also being able to develop. even Lille was quite confident in playing the ball in their own defense when getting pressure from Madrid players.
It was surprising that Madrid could not chase the 1 goal after trying to play Mbappe, Modric, and also Arda Guler. I thought at least they would play with both of them to score. but that didn't happen. a pretty bad result for Madrid.
Real Madrid did not have the opportunity to break their defensive line, which is why the one goal stand and Lille finish the game with three points. Madrid are the favorites to win the game because Lille are not in better form, but they get the chance to win Madrid in the UCL, the fans motivate Lille very well, and they do everything they can to prevent Madrid from scoring a goal, and they get the opportunity to end the game with a one-goal victory for them. I can't blame the players because they do their best, it's just that they didn't get the opportunity in the match because they do well on the pitch, and if it's the second leg, I'm sure Madrid will definitely defeat them at home. Ancelotti will be very weak, because he won't expect that Lille can win them in the game but that is football, we usually see surprise in different matches in some competitions so is normally thing that madrid lose in the ucl, they finish last season without defeat and this time they didn't get the chance of keeping the records.
