Unai Emery’s overhaul of Arsenal will continue next week when the club finalise negotiations on the £25million transfer of Uruguay midfielder Lucas Torreira.

The fee with Sampdoria is close to being agreed and the deal is expected to be announced once Uruguay finish their World Cup campaign.

Torreira played the whole game as Uruguay beat Portugal 2-1 on Saturday to reach the quarter-finals of the World Cup.

Arsenal are set to finalise the signing of Uruguay midfielder Lucas Torreira for £25million

Last week Sampdoria president Massimo Ferrero confirmed that Torreira was set to leave the club.

'Torreira's gone for €30m (£26m),' Ferrero told Italian television channel Sportitalia.

'I bought him from Pescara when nobody believed in him. We gambled on him and we won, paying just €3m. The money we're earning is necessary to increase our club's capital.

'If we get a big offer for somebody, I will accept it, but we don't need to sell our players off at bargain prices.'

It comes as Arsenal prepare to announce the £17m signing of Sokratis Papastathopoulos from Borussia Dortmund. The Greek centre half has completed his medical at the club.

Arsenal have already signed Bayer Leverkusen goalkeeper Bernd Leno for £19m and 34-year-old Swiss full-back Stephan Lichtsteiner on a free transfer from Juventus.
