Pep Guardiola will embark on a ruthless £200million summer overhaul at Manchester City - with Vincent Kompany the biggest victim of the clear out.

City boss Guardiola wants to sign at least four new defenders after his side’s embarrassing Champions League defeat to Monaco saw them go out at the last 16 stage .

Kompany, who has been plagued by injury for the past two seasons, is set to be the most high-profile casualty, after travelling to Monaco but failing to even make the bench.

According to City sources, Kompany was “100 per cent fit” and ready to play, but Guardiola chose to omit him from his 18-man squad, with the defender said to be unhappy at the snub.

The Belgian, 30, is one of several defenders set to leave City this summer along with Bacary Sagna, Gael Clichy and Pablo Zabaleta.

Sagna has been offered a one-year deal by West Ham, Zabaleta and Clichy have been told they are free to find new clubs, while goalkeeper Willy Caballero is still waiting to learn if he will be offered an extension.

Although he has been unconvincing at centre-back and was at fault for Monaco’s decisive third goal that knocked out City, Aleksandar Kolarov is not thought to be under threat.

John Stones and Nicolas Otamendi are also safe, but Guardiola believes he needs virtually an entirely new rearguard if City are to have any chance of being a force in the Champions League.

City have already identified several defensive targets, Juventus and Italy centre-half Leonardo Bonucci , Valencia left-back Jose Gaya and Bayern Munich’s Joshua Kimmich, who can play at right-back and in midfield.

Caballero has been promoted to first-choice keeper after Claudio Bravo’s ongoing gaffes finally persuaded Guardiola to ditch the man he brought in to replace Joe Hart.

But Caballero is a short-term solution for Guardiola, who wants to be reunited with another of his former Bayern charges, Manuel Neuer, although City know it will be tough to land him.

Midfielder Yaya Toure is also out of contract and will leave, while doubts remain over the future of striker Sergio Aguero, who is wanted by Real Madrid and lost his place to teenage sensation Gabriel Jesus, before the Brazlian was sidelined through injury.

City are also set to offload four players currently on loan - Joe Hart, Samir Nasri, Wilfred Bony and Eliaquim Mangala - which means there could be up to 10 players leaving this summer.
