While footballers have individual differences in their talents and abilities, it's next to impossible for any footballer to perform to their best possible abilities in every single match.Reasons for underperformance in footballers can be one or many. A common reason is often a persistent, minor injury that hampers a player's performance. There could be other issues as well, like a footballer playing for a club they no longer want to be at.Given how underperformance can happen with any footballer, even world-class players can face spells of poor performance. Great footballers can often jump back from poor spells easier than others. This will be the priority of the next five names from the world of football who have played well below their abilities in the current season so far.#5 NeymarClub Brugge KV v Paris Saint-Germain: Group A - UEFA Champions LeagueVery few footballers carry a reputation like Brazilian superstar Neymar in modern times. The Brazilian has won several trophies, and has already played for two of the biggest clubs in Europe—Barcelona, where he won the treble, and Paris Saint-Germain.At Barcelona, he formed a deadly trio with Luis Suarez and Lionel Messi, with the latter also being his teammate at PSG presently. His world-class abilities led the French giants to trigger his previous clause and break the then world transfer record for a fee of €222 million.Sportskeeda Football@skworldfootballAccording to reports, Neymar might not recover from an ankle injury in time for the first leg of PSG's Champions League clash against Real Madrid. 😳🤦🏼‍♂️#PSG #UCL #RealMadrid #Neymar4:17 AM · Dec 23, 2021132According to reports, Neymar might not recover from an ankle injury in time for the first leg of PSG's Champions League clash against Real Madrid. 😳🤦🏼‍♂️#PSG #UCL #RealMadrid #Neymar https://t.co/3v9tgqbz1FBut the mercurial talent that Neymar boasts hasn't been tapped into during the current season.
