Bayern Munich striker Robert Lewandowski is reportedly "ready to play" in the second leg of his side's UEFA Champions League quarter-final second-leg meeting with Real Madrid on Tuesday after recovering from a shoulder injury.
The Portugal worldwide netted twice in the first leg of the Champions League quarter-final tie to hand Madrid a 2-1 lead ahead of the return and Ancelotti is desperate to avoid a repeat of last week's scenario. "We'll not gamble. The first leg is already in the past and we know the difficulties Bayern can create".
Carlo Ancelotti: "Small details decided the first leg and we have to focus on those. But we have a lot of important games and tomorrow we'll see what happen".
Bayern has only managed two wins in 12 matches against Madrid at the Bernabeu.
Madrid have entered a pivotal week in their season, hosting bitter rivals Barcelona - who they hold a three-point advantage over and have played one game fewer than - in what could prove to be La Liga's title decider on Sunday. Their two defeats during that time were against Barcelona in April 2011 (0-2) and Schalke in March 2015 (3-4).
Bayern badly missed their injured leading scorer last week, but now he's back and they must make the very most of his firepower by giving him plenty of ammunition.
Isco stood out with two goals including a last-gasp victor in Saturday's game, but he has been used sparingly in Europe this season, getting just 77 minutes in total across Madrid's nine Champions League games to date. He is three short of the 100th-goal mark in the Champions League.
And with a new contract signed just previous year, he will hope to keep on breaking goalscoring records for some to come at Real - starting with reaching 100 in the Champions League.
The prolific Portuguese netted twice against Bayern Munich to reach a century of European goals.
Bayern had been the dominant home team in the Champions League until last week's loss ended its run of 16 consecutive home wins.
Bayern Munich have only kept one clean sheet in their last eight Champions League games. In the knockout stages, he's scored 0.72 goals per game (46 in 64 games), a better rate than in the group stages (0.71). Overall, he has nine goals in European Championship Finals and is tied with France icon Michel Platini. If he plays, it will be his 100th game in the competition.
Bayern Munich's last three goals in the Champions League have all been scored by Arturo Vidal.
