#2 Win the Champions League with Manchester City or Paris Saint-Germain

Manchester City and Paris Saint-Germain have spent millions in their pursuit of Champions League success, but neither team has tasted triumph yet.
Paris Saint-Germain reached the finals of the competition in 2020, while Manchester City did the same last season. Bayern Munich and Chelsea triumphed during those occasions, and both clubs have continued to invest heavily this summer as they seek to win Europe's most prestigious club competition.
Lionel Messi could prove to be the X factor. His world-class ability has often been the difference between a Barcelona win and a Barcelona loss, and whoever signs the diminutive attacker will be the favorite to win the competition this season.
#1 Lionel Messi could win a different league

Lionel Messi has won La Liga ten times. However, as mentioned before, comparisons have been made between Messi and Cristiano Ronaldo, with Ronaldo having won the league in three different countries.
Both Paris Saint-Germain and Manchester City have been dominant forces in their respective leagues in recent years. While Manchester City are the defending champions of the Premier League, Paris Saint-Germain's monopoly of Ligue 1 has been well-covered, and it was a surprise to see Lille beat them to the league title last season.
Messi stands an excellent chance of winning in the league in England or in France if he decides to move to one of these clubs. The 34-year old boasts an overflowing trophy cabinet and could soon add to his medal haul.
