L.Messi seriously considers the possibility of becoming a free agent

The upcoming months will be very restless for the leaders of "Barcelona".

They are facing a serious threat of losing team leader Lionel Messi as soon as next summer.

The 30-year-old Argentine has not yet signed a new contract and, as reported by the radio station "Onda Cero", is seriously considering not doing so.

If that were to happen, the global superstar could start negotiations and sign a future contract with another club as soon as January.

This summer, there were reports that L. Messi was ready to commit to "Barcelona" until 2021 and the contract was supposed to make him the highest-paid footballer.

Over the years, the sniper could earn 22 million euros after taxes.
