Following the UEFA Champions League last-16 exit, Manchester City have identified AS Roma defender Antonio Rudiger as their next big-money defensive signing.
Pep Guardiola is reportedly unhappy with the performances of his defence this season, despite having one of the most expensively assembled back-lines in Europe.
The likes of John Stones, Aleksandar Kolarov and Nicolás Otamendi have been consistent for their inconsistencies despite a combined transfer fee of £104m, while £42m flop Eliaquim Mangala is on loan at a struggling Valencia side.
Captain Vincent Kompany's chronic injuries has also left a huge hole in terms of leadership and general defensive stability for the Citizens, who've conceded a total of 50 goals in 47 games.
Rudiger, a full senior Germany international has attracted the attention of Chelsea, Arsenal and Bayern Munich over the past 12 months but according to the Daily Mirror, Guardiola wants the Serie A star to lead his backline next season.
The £30m rated 24-year-old defender is currently in Joachim Löw's squad to face England next week.
