Manchester City line up £11m bid for Hamburg's

Jerome Boateng and Osasuna's Cesar Azpilicueta

Manchester City will revive an £11m move for German international defender Jerome Boateng in the summer.

Manager Roberto Mancini, who also dispatched scouts to watch Osasuna right-back and long-time target Cesar Azpilicueta this week, is planning a major squad overhaul centring on his defence.

Hamburg centre-back Boateng, 21, whose contract says he can leave for £11m, has inspired his club to the Europa League quarter-finals and sixth place in the Bundesliga. His brother Kevin-Prince is due to leave Portsmouth this summer.

The Germans want 6ft 3ins Boateng to extend his current contract to 2013. However, he is keen on the challenge at City and could be joined by Azpilicueta - even though Osasuna want £15m for the 20-year-old Spaniard.

City scouts have watched Azpilicueta all season after Mark Hughes was initially alerted to him. They were once again spying on him during Osasuna’s 2-0 defeat to Barcelona on Wednesday but he has a contract until 2014 that would make his purchase costly.

Thommo call to Kop star

The former Kop skipper feels such an ultimatum will be the best way to turn up the heat on American owners Tom Hicks and George Gillett.

Thompson reckons the star pair could smoke out the unpopular Yanks by telling them to back boss Rafa Benitez with a transfer kitty in the summer.

Anfield legend Thommo rapped: "Fernando Torres said he didn't want to be fighting for fourth place every year - and he is absolutely bang on.

"He and Stevie Gerrard should be saying 'If you're not going to invest, why would we want to remain here?' They need to give them some ultimatums."
