Is 4-5-1 a good formation and what are the weaknesses?

That is infact the newly common 4-2-3-1 formation that football sides use today, where teams can make players attack and defend in many different situations, Theres only one front man but with 3 possible players to support him in a attack and like wise they can send players back to defend, this formation by many is believed to be 4-4-2's successor. The weakness is attacking players need to get back and defend.
