A year ago, Manchester City pursued star Arsenal midfielder Samir Nasri all summer, eventually signing him for £25 million on August 24.
Arsenal had to scramble to replace the Frenchman, managing only to bring in Chelsea's Yossi Benayoun on loan, and have only, a year later, signed his replacement(s) in Santi Cazorla and Lukas Podolski.
Much the same scenario appears to be unfolding with Liverpool centre-back Daniel Agger, and, unless Brendan Rodgers moves now, his Liverpool side could be put in the same situation as Arsenal a year ago.
With Roberto Mancini's ruthlessness in the transfer market, a move seeing Agger leave Anfield to join the Premier League champions might be inevitable.
It could be a good idea for Rodgers and his Reds to make a move to find the 27-year-old Dane's replacement now.
Liverpool will likely look for around £30 million for Agger's services and that money will be reinvested in the transfer market.
Here are five potential replacements Liverpool could look at should Daniel Agger move to Manchester City.
You wouldn't know it, but Daniel Agger's departure might just prove to be a blessing in disguise.
Brendan Rodgers has a number of talented youngsters seemingly ready to break into the first team, and with Agger out of the picture, it might be high time to promote prospects like Sebastian Coates and Martin Kelly into the first team.
They respectively made 34 Premier League appearances combined last season and, by all accounts, appear ready to become full-time contributors for the Reds.
Not only would putting those players alongside Martin Skrtel in the starting XI and running with that team allow the Reds to begin a youth movement that would see players like Conor Coady and Raheem Sterling earn permanent spots in the first team, but it would also allow the Reds to invest however much they receive from the Agger sale into other, more pressing needs.
Like an elite new center-forward or left-winger.
"Ash is in the top four centre-halves in the country in my opinion."
Then-Swansea manager Brendan Rodgers' quote, from the Daily Mail in March, says it all about how highly the new Reds boss thinks of 27-year-old Welsh international Ashley Williams.
"He has stepped up to the mark and shown he can play at this level."
A stockily-built defender who plays a similar game to Agger, Williams is extremely durable having made 190 appearances over the last four seasons and is already acclimated to Rodgers' playing system.
Williams may not be as attractive an option as some of the others on this list quality-wise, but he'd be a lot cheaper and would again allow the club to invest funds in other areas of the squad.
Regardless of Agger's transfer status, you would have to think Rodgers has considered the possibility of bringing Williams with him to Anfield.
With Liverpool coming out of somewhat of a rebuild, the goal has been with bringing in younger players with a high sell-on value.
But it wouldn't be surprising to see the Reds add some veteran experience to their side to complement the younger players—a quality 30-year-old Bruno Alves would certainly bring it.
A centre-back renowned for his strength and aerial ability, the Portuguese international would add much the same qualities that the club would lose with Agger's departure.
His 30 years and the likely £15 million price tag might be turn-offs for Liverpool, but Alves might be the best possible replacement of all in the short term.
Earlier in the summer, The Guardian suggested that Manchester City might look to let Joleon Lescott join Liverpool in order to facilitate Daniel Agger's move to the Etihad Stadium.
Lescott joined City from Everton in August 2009 for around £22 million and has since established himself as one of the Premier League champions' key players, starring alongside Vincent Kompany in the heart of City's defense.
But Agger's rumored move would inevitably force Lescott out of the starting XI and the 29-year-old could well leave the lucrativeness of City for more playing time.
A 29-year-old England international, Lescott would not mark much of a downgrade, if any, from Agger and would continue the Reds' recent tradition of acquiring homegrown players.
If Agger's move does go ahead, Lescott could well find himself a Reds player next season.
What better way to replace your star Danish centre-back than with another star Danish centre-back?
One of Europe's most promising young players for the past half-decade, 23-year-old Simon Kjær has never had the opportunity to prove his worth in the Premier League, but could find himself settling on Merseyside.
The tattooed Denmark international, who spent the 2011-12 season on loan at Italian AS Roma from Bundesliga club Wolfsburg, is a tough-tackling central defender who has in the past compared himself to ex-Barcelona defender Rafael Marquez in his style.
Kjær has the ball skills to come forward and be a part of the attacking game, making him a player who would fit well into Brendan Rodgers' style.
Roma are reportedly keen to extend Kjær's loan deal, but the Denmark youngster would undoubtedly prefer a permanent move to England.
Brendan Rodgers should lodge a bid as soon as possible for Simon Kjær.
