For the past decade and a half Lionel Messi has entertained football fans with his mesmeric dribbles,incredible goals,and his wide array of passes and assists. Given his consistency choosing Lionel Messi's best season seems an herculean task. But all in all Lionel Messi's best season seems to be the treble winning season of 2015. Some may argue that the 2009 treble winning season is Lionel Messi's best season but i beg to differ because in 2009 messi was still young and not fully developed as a player, he was still an upcoming star and he won his first Balon d'or that season. Come 2015 Messi had established himself as arguably one of the greatest players of all time, was more mature as a footballer and he was a part of the legendary attacking trident of the MSN; the most lethal attacking force of all time. But to prove my arguement i posted the link to a video that highlights messi's overall performance both in Dribbles, Passes, Goals and assists.
