Barcelona lost to Inter in the semifinals only because they were rushing and didn’t take advantage of their chances. Inter relied on their experience and waited until the end
I think Barcelona didn't rush this match at all, but they couldn't win it despite all their efforts.Perhaps it should be understood that Barcelona Football Club and Inter Milan Football Club applied different patterns and different strategies in that match, and even their formations were different. In that match Barcelona Football Club emerged as a balanced team but they did not show the good skills we had hoped for against the Italians.
I think if Barcelona had made it to the final, we would have seen a much better match than the one between PSG and Inter. Inter looked very bad and physically unprepared.Regarding the players, as you mentioned, if someone gets injured, of course they need to have good players on the bench. I believe Barcelona’s management will make some very good moves in this transfer window.
Of course it is plausible that if the final match had been between Barcelona and Paris Saint-Germain, it might have been more spectacular and much more competitive.
Before the Champions League semi-final match, many were of the opinion that Barcelona was progressing miraculously and that they had not lost a match so far so maybe they will be a worthy candidate for the UEFA Champions League final.
