It looks highly unlikely that they will qualify for the knockout stages of the UEFA Champions League unless something dramatic happens.How will Barcelona's Champions League debacle affect Lionel Messi's chances of a return?PSG superstar Lionel Messi is linked with a return to BarcelonaLionel Messi left Barcelona in 2021 as the Spanish club were unable to renew his contract after failing to comply with La Liga's wage cap rules. He joined PSG on a free transfer.While he struggled in his first season at the club, scoring 11 goals and providing 15 assists in 34 games, the Argentine has found his feet this season. He has scored eight goals and provided eight assists in 13 games so far.However, his contract with the French club is set to expire in June and a return to his boyhood club could be on the cards.The Catalan club are currently the league leaders in La Liga, with 22 points on the board from eight games. However, they have struggled in the UEFA Champions League yet again.Messi's current club, PSG, meanwhile, are on their way to the knockout stages with eight points on the board from four games. With Neymar Jr. and Kylian Mbappe combining with the Argentine legend, the Parisians have a real chance of lifting the trophy.Whether Messi decides to leave the star studded PSG team and potentially hamper his chances of winning major trophies by returning to the struggling Barcelona side remains to be seen.
