WATCH: Alvaro Morata celebrates against former club Real Madrid

On Tuesday, Real Madrid hopes to win back-to-back games in the Champions League league phase after defeating Borussia Dortmund in a thrilling comeback on MD3.  Carlos Ancelotti's team defeated Borussia Dortmund of Germany by five goals in their last Champions League match. Real Madrid won handily thanks to a hat-trick from Vinicius Junior. Now, their next goal will be to match AC Milan with a similar showing. In the early going, Carlo Ancelotti's team has fallen in their match against AC Milan at the Santiago Bernabeu.

Real Madrid have given up the lead in this tournament for the third straight game. This time, Milan's goal came from German defender Malick Thiaw. Christian Pulisic sets up a beautiful corner, and Thiaw's hard header puts Andriy Lunin in goal. Thibaut Courtois's comeback is taking longer than anticipated, and he has little chance of keeping the ball out of the net.

But soon before halftime, AC Milan took the lead again, when Alvaro Morata scored against his old club. Leao turned and struck a low shot that Lunin saved well but went directly into Morata's path as Pulisic darted towards the right edge of the box and offered a cut-back. Shutting down the supporters of his old team, he tucked it ball from close range.

Real Madrid struggles to keep lead

Malick Thiaw put the visitors ahead, but the lead was only maintained for 10 minutes. Vinicius Junior scored from 12 yards out to complete the win after Emerson Royal fouled him inside the penalty area.Vinicius coolly flicks the ball into the middle of the Milan goal for a penalty after waiting for Mike Maignan to dive. This is the Brazilian superstar's fourth Champions League appearance this season, and he is now up to nine in all competitions.

It's a catastrophe for Real Madrid, and if they want to win this game, they'll need to put on another strong second-half effort.
