Arsene Wenger has confirmed that Shkodran Mustafi and Lucas Perez have both passed medicals ahead of their moves to Arsenal, with the deals set to be announced next week.
The Gunners moved on Thursday to trigger a £17 million release clause for Deportivo La Coruna striker Perez, while British media then reported that evening that the club had also agreed a £35m fee for Valencia defender Mustafi.
Speaking after Arsenal secured their first Premier League win of the season with a 3-1 victory at Watford, Wenger said that the deals for both players are all but done, with just the necessary paperwork still to be sorted out.
"I think they should go through, both of them," Wenger told a news conference. "We have to finish the paperwork. I don't know exactly when we will announce it. But I think it will be announced early next week."

Wenger added to Sky Sports: "We have bought two players -- Mustafi and Perez. They will integrate into the team now and we will help them join the squad.
"We had to work very hard to get the signings done. We have not got any plans for anyone else now."
If the deals are completed as expected, Wenger should be able to call on both players after the international break.
Mustafi will add experience to the back four after Per Mertesacker and Gabriel Paulista were both injured, forcing Wenger to start 20-year-old Rob Holding in the Gunners' first three games. While Holding has impressed, Mustafi is likely to form a central defence partnership with Laurent Koscielny going forward.
Wenger has tried to sign a striker all summer and finally settled on Perez after failing to land Jamie Vardy or Alexandre Lacazette. The 27-year-old Perez scored 17 goals in the Spanish league last season, adding eight assists, and should compete with Olivier Giroud for the starting job up front.
Perez offers a different playing style to Giroud as he relies more on his pace than size, and can be dangerous outside the area as well as in the box. While Perez was relatively unknown before his breakthrough last season, Wenger has called him a late bloomer who has benefited from being converted into a striker late in his career.
"I think he has good linkup qualities, good quality of receptions, good finishing qualities," Wenger said about the Spaniard ahead of the Watford game.
