A section of Real Madrid fans online are not happy with the inclusion of Toni Kroos in the starting XI for their second-leg fixture against Manchester City in the Champions League semi-finals on Wednesday, May 4.Los Blancos are currently 4-3 down from the first leg but have home advantage to rely on in the second leg of the tie.Toni Kroos has been one of Los Blancos' most important players over the past few seasons. However, the German midfielder has had indifferent form this season. Kroos has slowed down due to his age, which has resulted in a weakened midfield. His stocks have also dropped since the arrival of Eduardo Camavinga last summer.Real Madrid fans on Twitter believe that Toni Kroos should not have started in arguably their most important game of the season so far. Many have also suggested that his inclusion gives Manchester City a clear advantage in the tie.Here are some tweets in that regard:Ballon D’Or Hater@DotunRCAKroos?

The 32-year-old midfielder had a lackluster game at the Etihad Stadium. However, he was deployed as a defensive midfielder due to the absence of Casemiro.Toni Kroos has made 39 appearances for Real Madrid this season, with 10 of them coming in the Champions League. The former German international has contributed three goals and three assists this season across all competitions.Real Madrid or Manchester City will face Liverpool in the finalEither Real Madrid or Manchester City will face Liverpool in the Champions League final in Paris later this month on May 28.
