Manchester City are set to finalise the signing of Ilkay Gundogan in a £21.6million deal in the next 48 hours, Football Insider sources understand.

City have reached an agreement to capture the Germany midfielder but held back from pushing through the deal amid fears it would get little attention following the arrival of Jose Mourinho at Manchester United last week.

A City source has told Football Insider that City will announce the signing of the 25-year-old later this week, and most likely within days.

There had been some doubts over whether City would opt to conclude a transfer with Borussia Dortmund after the player suffered a dislocated knee cap earlier this month that will prevent him from playing at Euro 2016 and force him to miss the start of next season.

But incoming City manager Pep Guardiola has not been put off by Gundogan’s lay-off and asked the club to push ahead and complete what will be his first signing at the Etihad Stadium.

Talks are expected to be finalised with Dortmund and Gundogan’s representatives in the coming days. The fee is set to be worth a total of £21.6 million including performance-related add-ons.

Gundogan, 25, underwent surgery on his knee a fortnight ago and is expected to be out for around four months.

Midfield anchorman Gundogan has been impeded by a series of injury problems in recent seasons but Guardiola and City’s director of football Txiki Begiristain are convinced he will bring more energy and control to a midfield found wanting in recent seasons.

Gundogan joined Dortmund from Nuremberg for £4million in 2011 and has established himself as one of Europe’s most sought-after midfielders.

He signed a contract extension last summer but it is due to expire in 12 months and the German club decided to cash in once it became clear the player wanted to move.

In other Manchester City transfer news, the 2014 Premier League champions have opened preliminary talks to sign a striker who scored 39 goals for his club this season.
