The difficulty of deciding who to play for Real Madrid, which has many star players, does not upset Ancelotti. Training performance is very important for Ancelotti. Moreover, these players will bring all kinds of success to the team. Real Madrid will scare every rival team next year
Ancelotti seem like a person who is not bothered about the number of stars available but with the current squad depth i think he will be quite bothered, there are lots of players already and with more joining up with the squad soon and we don’t know yet how many players will be added during the summer transfer window with only few players leaving so managing them could be a problem. Selection would have to be based on performance that means every player would have to fight for their spot.
No, with so many great players at Real Madrid, Ancelotti will be more comfortable to choose players and provide rotation to maintain fitness. In fact, I'm sure he would be happy if he had 22 players who have great quality in every position. With that condition, of course, the opportunity to get many titles is increasingly open. Just look when he has players playing in the Euros, of course Ancelotti will feel happy because he is helped to maintain the fitness of the players.
It’s not as easy as it may seem especially when all the players are performing well, Having many players is good in case of injuries but selecting a starting lineup may be difficult. All the players joining Madrid so far are talented players that cannot be benched else it would look as if the talent are being wasted. Player like Arda Guller and Endric are great talents that needs players time to develop into stars but i trust Ancelotti to manage them all properly.
