I'm thinking of Liverpool in particular, who usually start the season worse, but in the second part of the season they play much better and achieve much better results.
If they were to play their match against Real now, they wouldn't have much of a chance, but I'm sure that in the spring they will be much better and more ready for the match with Real.
In any case, a very uncertain and exciting competition awaits us, and we still do not know in what condition the players will return from the world cup.
Nonetheless, it appears Klopp has benefited from the World Cup hiatus. as we predicted, if Liverpool played their match with unstable team performance conditions. many of us predict, Liverpool will be powerless against Madrid in the round of 16 later. however, by having a long break due to the world cup break. Klopp, can rearrange his troops and restore the mentality of his troops, plus provide time off for the recovery of injured players.
I hope that after the world cup break ends, Liverpool can show their best game against Real Madrid.
I think these types of breaks are better for those teams which are underperforming. And these types of brakes is not good for those teams which are performing well and consistently, because this certainly takes out the momentum from them in my opinion.
But I think a team which is performing well is more likely to come back and start performing well regardless of a break unless they have injury issues. And this is one thing that clubs will have to be really careful about. But then again, they honestly cannot do anything if a player gets injured, trying to give his full effort at the World Cup for his national team.
