Nottingham Forest complete signing of Orel Mangala | OneFootball

Nottingham Forest have announced the signing of Orel Mangala from Stuttgart on a long-term contract.

The Belgium midfielder becomes Forest's 12th signing of the summer after they secured promotion back to the Premier League via the play-offs at the end of last season.

Steve Cooper has been busy reinforcing his squad ahead of the new campaign, with Mangala completing his move to the City Ground on Friday.

90min revealed earlier this week that Forest were in talks with Stuttgart over a deal for the 24-year-old, with the East Midlands side expected to pay around €15m for his services.

Mangala made his Belgium debut back in March and is in with a shout of making the Red Devils' World Cup squad despite fierce competition in his position.

Forest have been among Europe's biggest spenders this summer and seem keen to complete further deals. 90min understands they have held talks with Real Betis over William Carvalho and Alex Moreno.

Their Premier League campaign kicks off next Saturday with a trip to Newcastle United.
