There is much more hope that Ancelotti will be able to fit existing players, such as Hazard and Bale, in a much more effective way, building a more trusting relationship with them.
Yep, Ancelotti has a hard job to build a good relationship with the players and especially with those who have less opportunity to play or even got a loan in the last season. Also, he needs to bring back a good mentality and confidence in playing for such players as Hazard and Bale. These players need more motivation to play again on their best levels.
Hazard and Bale are both world-class players. It is almost impossible to resist them if they are in form. After Bale was injured very quickly, Ancelotti had to keep an eye on the matter. Benzema - Bale-Hazard Real Madrid will be able to give a stable performance if this trio is in form.
