I dont think that they are now dependent on messi as you can see that how good sqaraz played and scored goal and won for the team. But due to famous name of messi it is always used it for getting highlighted
You certainly did not watch the match played yesterday and i also doubt if you watched any games of Barcelona with Messi in the pitch and without Messi in the pitch. Otherwise, what you are saying here is totally incorrect.
Barcelona have been over dependent on him lately and whenever he doesn't play, the results speak for themselves. Please first watch matches before making random conclusions.
