French superstar Kylian Mbappe's "ups and downs" are to be expected because of Real Madrid's demanding season and the nature of players of his quality, said coach Carlo Ancelotti on Saturday. The striker performed poorly against Atletico Madrid in the Champions League and previous La Liga match against Real Betis, just days after scoring a hat-trick against Manchester City. Mbappe struggled in his first few months at Madrid after joining last summer from Paris Saint-Germain before bursting into form, but his last couple of appearances have caused concern among fans.
