Does Barcelona pay the price of its exhausting calendar, or is it abundant?

Since March 27, Barcelona has played a total of seven games in 15 days, distributed between the Spanish League, the King’s Cup and the Champions League.
On that date, and what followed, Barcelona faced both Osasuna (3-0), Girona (4-1), Atletico Madrid (1-0), Real Betis (1-1), Prussia Dortmund (4-0), Liganis (1-0) and Borussia Dortmund (1-3), meaning that he played seven games in 15 days.
This exhausting situation seemed clear to the players in the last game against Dortmund, especially when they got on the ground and the signs of exhaustion are clear to them.
The series is not over, as Barcelona will have to face Celta Vigo (Saturday, April 19), Real Mallorca (Tuesday 22) in the league, and Real Madrid (Saturday 26 of it) in the King’s Cup final.
After that, Barcelona will have to confront Inter Milan (Tuesday 30) in the first leg of the Champions League semi -final, then Valdolid in the league (on Saturday 3 May), then Inter Milan in Milan (Wednesday 6), then Real Madrid in the second leg of the league (11 of it), Espanyol (14 of it) and Verial (18 of it), before he relaxed for days and faces Athletic Bilbao at the end of the local championship (25 of it).
This means that Barcelona will play between 19 April – April and May 18 – May, a total of 9 games in 30 days, with a team that will not exceed 3 and a half days between the match and its sister. Will the price of that pay and this hard season ends with wholesale titles or some of them or perhaps … nothing?
