Lionel Messi wants out at FC Barcelona following their 8-2 quarterfinal loss to Bayern Munich in the Champions League, according to journalist Marcelo Bechler. The 33-year-old Argentine superstar's contract is set to expire next summer, but Bechler says, citing club sources, that Messi wants to leave now. 

That will put clubs with the biggest financial resources -- such as Manchester City, PSG and Juventus -- on high alert.

Messi hasn't spoken publicly after the loss to Bayern Munich, but such a decision wouldn't be all that shocking. However, we've seen Messi say he would retire from the Argentine national team on two occasions before coming back. His future at Barcelona has been up in the air for a while now, and contract talks stalled in July.

Messi and Barca went without winning a trophy this season for the first time in over a decade. The team failed to make a deep run in the Copa del Rey, lost La Liga to Real Madrid and once again had another European nightmare in UCL. On top of that, the club fired coach Ernesto Valverde in January for the soon-to-be-sacked Quique Setien, while Messi also clashed with the club's higher-ups.
