Raheem Sterling: Can Manchester City's new £49m man make them challengers?
The waiting is almost over as the greatest show on earth prepares to roll up once again with this season's Premier League campaign one of the most eagerly awaited in years.
Manchester City pulled off the close season's biggest piece of business - thus far - with the capture of Raheem Sterling and the question is, can their new £49m turn them into title challengers?
The splashing of that cash has allowed Brendan Rodgers to go on another spending spree at Liverpool while over at Old Trafford Louis van Gaal hasn't been shy in dusting off the cheque book either.
Champions Chelsea have been reasonably quiet, with Jose Mourinho looking to succeed where Van Gaal failed in making Radamel Falcao look like a world-class striker while at the other end of the table, there will be the usual fight to avoid the drop.
Here we look at some of the key questions that will be answered over the coming months.
Does Raheem Sterling answer all of Manchester City's issues?: There are plenty of problems that Raheem Sterling has solved for Manchester City simply by signing for them: namely their lack of pace, youth and English players. That is why they paid £49m for him and gave him a £47m contract. He will certainly improve City quickly.
But other questions are left unanswered: who is the best partner for Vincent Kompany in defence? Where is the incision from out wide when all four full-backs are in their thirties? What is Fernando meant to be doing? Sterling is good but he can't do everything.
Can Arsenal win the title with Olivier Giroud up front?: When Thierry Henry said last season that Arsenal needed a "top, top striker" to win the league, he reopened the longest-running debate in north London: can you win the title with a striker who is good but not great? Giroud has been an admirable servant over the past three years, and a bargain at £10m. But his big-game record suggests that he will never be on the level of strikers who win you titles: Diego Costa, Sergio Aguero, Robin van Persie. Arsenal are an efficient, experienced unit. It remains to be seen if their spearhead is sharp enough.
Have Manchester United finally found their centre?: The empty space in United's midfield has been the difference between them and the best of England and Europe for the past few years.
They have been too old and too slow for too long, overtaken by Manchester City and Chelsea. This may now have changed. The same-day deals for Morgan Schneiderlin and Bastian Schweinsteiger - both experienced, powerful, authoritative players - should fill that gap. Combined with Michael Carrick and Ander Herrera, they should finally have the numbers and the quality to control games against the best. The onus is on Van Gaal to find a way to make it work.
Can anything stop Chelsea?: After the drama of 2013-14, last season's title race was one of the weakest in years. Chelsea were so far ahead in every meaningful way that it was barely a contest. Unless Arsenal or the Manchester teams improve beyond expectation, the likeliest challenge to Chelsea retaining the title will be internal. What if John Terry's age catches up with his body? Even pairing Gary Cahill and John Stones would not be the same. What if Costa's hamstrings and temperament cost him games and Radamel Falcao (pictured) is no sharper than he was at United last season?
Have Liverpool worked out their route to goal again?: As Rodgers was not averse to telling people last season, Liverpool had lost almost 60 goals from their side that nearly won the title in 2014. That, in short, explained their slip from thrilling second place to dismal sixth. This summer Liverpool have gone out to buy those goals back.
Roberto Firmino is a talented but expensive attacking midfielder signed for £29m from Hoffenheim. Danny Ings is a lively player who is completely untested at the top level. And Christian Benteke was an excellent battering ram for an average team. Whether he can adjust to lead the line for Liverpool may decide Rodgers' future.
Can Everton rediscover their cut and thrust?: The depressing thing watching Everton last season was the slowness of it all. The pace and spark of the previous season had dissipated and they were playing boring, sedate, predictable football.
So Roberto Martinez has brought Gerard Deulofeu back from Barcelona and picked up Tom Cleverley on a free transfer. Those two should liven up the team. But is that the whole solution, or will last year's defensive problems hold them back?
Will this summer's new signings fit in quickly?: Stoke City's growth under Mark Hughes has been a pleasure to watch but they now have the potential for more after signing Ibrahim Afellay from Barcelona.
Afellay came on in the 2011 Champions League final and could be a thrilling purchase.
Swansea City's recruitment of André Ayew from Marseille is almost as much of a coup, as is West Ham signing Dimitri Payet from the same club.
Is Palace's Yohan Cabaye the player he used to be? The Frenchman was one of the best midfielders in the Premier League during his first two years at Newcastle, before his head was turned.
He could have stayed on the Paris Saint-Germain bench but if he can reach the level of 2012, Palace could be quite a side this year.
How damaging will the Europa League be?: The evidence is undeniable: participation in the Europa League impedes Premier League form. This year there are four English participants - provided West Ham United scrape into the play-off round - which could distort the top half of the league table.
For Southampton and West Ham, there is a novelty about being in Europe. For Spurs and Liverpool, though, the novelty has gone and it could be a slog.
Will any of the three promoted teams survive?: Last season, Burnley kept the team that took them out of the Championship but it was not quite enough. Queen's Park Rangers, over the years, have signed too many players and it has not worked either.
This year, there are competing approaches. Norwich have stuck with last season's side. Watford have signed a whole new team. Eddie Howe's Bournemouth have made a few clever additions to last year's miracle workers. But which, if any, will get 38 points? That's what makes this league so fun.
