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.
