I blame Pep for reacting too slow today. Sterling was never going to score today. Awful not to take him out. DeBruyne is another shocking player. You need to sub these guys at half time.
Messi can and will be the difference maker as long as Mbappe is there to provide the speed and directness. Luckily, Mbappe will be gone next season and then it will be the Brazilian clown and Messi - which will be an absolute shitshow.
