Fortify in a fortnight or risk losing ground early to top-flight foes.
Such are the motivations of managers and sporting directors across the continent, and with the summer transfer window set to slam shut in two weeks, some of Europe's biggest clubs still have glaring holes to fill.
With that in mind, here's a look at some of Europe's top-five tier title threateners and needs that must be addressed while the opportunity is available:
Premier League
Chelsea - From Premier League holder to title favourite to minor meltdown, Chelsea's shock defeat to Burnley at Stamford Bridge hinted that Antonio Conte's midfield is a bit thin. Inexplicably, Nemanja Matic and Nate Chalobah are gone while N'Golo Kante is left with just Tiemoue Bakayoko and a defensively disinterested Cesc Fabregas to pair with in the middle. This has prompted speculation of a move for Leicester City's Danny Drinkwater, who is more a stopgap than a long-term solution.
Arsenal - First and foremost, Arsenal needs sales. Mathieu Debuchy, Kieran Gibbs, Carl Jenkinson, Calum Chambers, Joel Campbell, Lucas Perez, and, arguably, tough-tackling tandem Gabriel and Francis Coquelin all need to be sold before Arsene Wenger can again dip into the market. That, paired with the expiring deals of Alexis Sanchez, Mesut Ozil, and Alex Oxlade-Chamberlain looming large, has the Gunners treading water in transfer window uncertainty for the 131st consecutive season.
Manchester United - The additions of Matic and Romelu Lukaku have breathed life into a Manchester United side that appeared limp in attack a year ago, though there are still some concerns at full-back. Antonio Valencia, 32, continues to be one of the league's most underrated players, though Daley Blind, Matteo Darmian, and Luke Shaw hardly amount to a core of wide defenders that matches a squad with title ambitions. Paris Saint-Germain wantaway Serge Aurier and Jose Mourinho's countryman Ricardo Pereira would fit the bill.
Liverpool - Anticipating that Barcelona target Phil Coutinho will stay put, Liverpool's most obvious need is a defensive boost. While a big-money move for Southampton's Virgil van Dijk would help spell either Joel Matip or Dejan Lovren, the Reds' deficiencies at the back can't be fixed by only one player. Conceding more set-piece goals than many unattended nets, Liverpool needs a leader at the back to encourage the likes of Roberto Firmino and Mo Salah to chip in when defending dead-ball situations.
Manchester City - What do you get the squad that has everything? Apparently, a third world-class forward. Reportedly looking to improve a frontline that boasts Gabriel Jesus and Sergio Aguero, Manchester City gaffer Pep Guardiola is hoping to lure his former Barcelona pupil Sanchez to the Etihad. That seems excessive, especially considering City's bench is better than many starting XIs, with Raheem Sterling, Bernardo Silva, and Leroy Sane coming off the pine in Saturday's win over Brighton. What does City need? Nothing. Moving on.
Tottenham - Tottenham chairman Daniel Levy spent more on his morning coffee than he has in the summer window, and with Kyle Walker off to City and Danny Rose's moans and groans linking the England international with an exit, Spurs need depth at full-back. The temporary Wembley dweller could also use a better second-choice striker than Vincent Janssen, but, more importantly, Kieran Trippier and Ben Davies need some help. Both Pereira and Aurier have been connected with a Spurs switch, while Ajax's Davinson Sanchez would be a massive upgrade at the back for AWOL Kevin Wimmer.
La Liga
Real Madrid - With depth that rivals the Mariana Trench, the only potential upgrade double winner Real Madrid could entertain is in goal. Pity Costa Rica No. 1 Keylor Navas - who has won seven trophies in four seasons at the Santiago Bernabeu - because the current first-choice shot-stopper is perpetually linked with replacement by either David De Gea or Thibaut Courtois. Does Real need a new 'keeper to replicate last season's exploits? No. Does that mean Florentino Perez will stop staring through the shop window at the aforementioned pair? Nay.
Barcelona - There's a gaping void on the left side of Barcelona's attack left vacant by Neymar's move to PSG, but that's not the Catalan behemoth's only concern. Andres Iniesta and Sergio Busquets both displayed signs of mortality last year, and already this pre-season, centre-halves Gerard Pique and Samuel Umtiti have been turned more than the handle on Josep Maria Bartomeu's bursting bank vault. Moves for Coutinho and Ousmane Dembele will help, but that's just the beginning for Ernesto Valverde's lot.
Ligue 1
Paris Saint-Germain - With Unai Emery's charges set to end Monaco's one-year spell as Ligue 1's best, PSG appears stacked for a title run, though questions remain in goal. The job was Kevin Trapp's, who gifted it to Alphonse Areola, and with speculation suggesting a blockbuster move for Atletico Madrid's Jan Oblak, the capital club looks like an outfit anxious to make a second shock summer swoop.
Serie A
Juventus - Eyeing a seventh successive Scudetto, Juventus is again Serie A's best-equipped side, though a lack of pace and dynamism in midfield could hamper Max Allegri's plans. There are land masses faster than Sami Khedira, dreamy eyes Claudio Marchisio is 31 and coming off an ACL tear, and while Miralem Pjanic is the star in the middle of the park, the Bosnian is hardly one to win a footrace. With the failed move for Corentin Tolisso in the rearview, PSG's Blaise Matuidi appears to be the best solution, with reports linking the long-legged Les Bleus stud with a Turin switch.
Bundesliga
Borussia Dortmund - While rival Bayern Munich was playing busy Bavarian by bringing in Tolisso, Niklas Sule, James Rodriguez, Serge Gnabry, and Seba Rudy, Borussia Dortmund listlessly countered with the additions of Max Philipp, Mahmoud Dahoud, Omer Toprak, and PSG reject Dan-Axel Zagadou. The latter two are expected to bolster reticent centre-backs Sokratis and Marc Bartra, but that's hardly a grouping fit of a Bundesliga challenger. The days of Mats Hummels and a fit Neven Subotic at the Westfalenstadion appear long gone as Dortmund sticks with thrifty transfers.
