Above all, Messi got embarrassed when they played against Bayern Munich because they lost by a lot. The score was 8 to 2 and Bayern Munich won against them in the quarter-finals. He got so embarrassed that he wanted to leave Barcelona. In the article called “What is the clause Lionel Messi triggered to leave Barcelona?” says “Ten days after Barcelona lost 2-8 to Bayern Munich in the quarterfinal of the Champions League, Lionel Messi has reportedly told the Spanish club that he wants to leave.” And not just Messi was embarrassed, the coach (Quique Setien) was also embarrassed. In the article called “Embarrassing Lionel Messi and Barcelona ‘was fun’ says Bayern Munich star Leon Goretzka” says “Quique Setien – who is expected to be sacked off the back of this latest embarrassment – could only watch on as Bayern Munich destroyed Barcelona 8-2 to reach the semi-finals of the Champions League.”
To continue, Messi wants to leave because he is bored of Barcelona. The team Barcelona has won a lot of Trophies and it seems that he is bored with it. In the article called “List of FC Barcelona records and statistics” says how many trophies the team won. “Domestically, Barcelona has won a record 74 trophies: 26 La Liga, 30 Copa del Rey, 13 Supercopa de España, 3 Copa Eva Duarte, and 2 Copa de la Liga trophies, as well as being the record holder for the latter four competitions.” In the article “Lionel Messi, Neymar and Barcelona Stars Are Bored, Claims Paul Scholes” says that not only was Messi bored in Barcelona, Neymar was also bored of Barcelona. “Former Manchester United midfielder Paul Scholes believes Lionel Messi and Barcelona's players have become bored.”
Finally, Messi wants to leave Barcelona because he had a clause in his contract that allowed him to leave Barcelona. In the article “What is the clause Lionel Messi triggered to leave Barcelona.” says that he had a clause in his contract to leave Barcelona. It said “He had a clause in his contract that allowed him to leave Barcelona. The clause was inserted due to a hefty buyout package, which would make a normal transfer unaffordable for most clubs.”
In conclusion, Lionel Messi wants to leave for the following reasons. The first reason is that he got embarrassed. My second reason is that he has been in Barcelona since he was 13 and now he's 33 years old. So he was in Barcelona for 20 years. My last reason is that he had a clause in his contract that allowed him to leave Barcelona.
