Carlo Ancelotti has attributed Real Madrid's "extraordinary" 19-match winning streak to the professionalism of his squad.
Los Blancos beat Ludogorets Razgrad 4-0 in the Champions League on Tuesday to set a record for the best run of victories ever by a Spanish side.
Despite having scored 71 goals during this period, Ancelotti has stressed that it is Madrid's serious attitude, and not their star-studded attack, which is the secret to their unparalleled success.
"It is not easy preparing for each game with the same levels of motivation and eagerness that these players are showing," the Italian told Real's official website. "After losing to Atletico [Madrid on September 13], I couldn't have imagined stringing together 19 consecutive wins.
"I was sure that the things that weren't going well would be fixed, but not to this extent. It is a result we have achieved with extraordinary seriousness and an incredible amount of professionalism. I know that I have an extraordinary group of players.
"I have a very good relationship with the players. I care a lot for them and I thank them for the work they're doing as much as I can. We are enjoying a great moment - the players, the technical staff and the club, which has always supported us. We have to keep this run going."
Madrid surpassed the 2005-06 Barcelona side's run of 18 straight wins with their triumph at the Bernabeu.
