Pep Guardiola, Arteta and Klopp are more experienced and dominated altogether top places these years. Not only their contributions driven their teams to that but also the contribution of the owners that offered top players and reinforced considerably the squad.
Manchester United are suffering from the inconsistency of the results although having good players and coach since the tactics used and the mistakes of the players are too much to maintain positive results. If there is something particular for Manchester United and Chelsea, is the money spent to purchase players and these signing turns to be overpriced and useless in many cases.
In the past few seasons, these three coaches have dominated the English league in particular, but for the highest competition in the Champions League, Pep Guardiola has outperformed his two rivals in terms of ability to manage a team. The three coaches have the ability to see the potential of players so that even if the players they buy are not well-known stars who have good qualities, they can always make the players more needed in the squad.
Man United, Chelsea and Tottenham are struggling to build a stronger squad but they haven't found a good rhythm, so they look very inconsistent. Chelsea are worse off, even though they spend a lot to buy players, but their ability to be in the Champions League and Europe is still quite difficult to achieve.
