He wants to break up the comfort some players seem to have found in not winning.
You nailed it.
Players like Shaw (first name I could think of), are constantly injured or not playing well enough to get into the first team. These players say the right things to the press, but behind closed doors, who knows what they actually do.
The other thing which nobody has mentioned in any thread, in any post is the "players in their prime argument".
This season CFC are winning the league. They have a team of players all in their prime. My understanding is that they have no young players being used.
Last season LCFC - all players in their prime.
The season before that, CFC won the league. I think a CFC supporter will need to correct me, but I believe Jose used players in their prime...no inexperienced young players.
The trend is that youngsters, who tend to be weaker (mentally and physically), just can't cut it at the very top (i.e. in a league winning team).
Even Tottenham (who have not won the league, btw), are using players now approaching their mid 20s or over 25.
IMO, the days when you can take time with youngsters to toughen them up, are gone. If you want to win the title, you need a team choc full of players who in their absolute prime (age, mental toughness, physical toughness and skill maturity).
If Jose is going to win the title next season (and the pressure will be huge to do this), I expect Jose to ditch the mentally weak players and stick with tough, fully grown men, with experience. Unfortunately, young players may have to give way.
