The BBC has confirmed that Arsenal will soon announce the signings of striker Lucas Perez and defender Shkodran Mustafi.
The two will have their medical later on today and will be officially announced in the early hours of Saturday.
If the transfers goes through, they will become manager Arsene Wenger's fifth and sixth signings of the summer transfer window.
Speaking on Friday morning, the Frenchman revealed that he expected the market to be "easier" and that he will be very busy in the next three days.
"It was a strange transfer market," he said.
"I expected it to be easier than ever but it was more difficult than ever. Not a lot has happened.
"It looks like when you meet other clubs and you have an English passport, you hit these [big] prices which are very difficult to understand compared to the quality of the players.
"It looks like it will be frenetic for me in the last three days. Everybody has sat on their pounds until now. We know they will all splash out now. I expect the next three days to be very, very busy, so be on alert!"
