Manager Arsene Wenger has confirmed that Arsenal will soon announce the signings of striker Lucas Perez and the defender Shkodran Mustafi.
The Frenchman was speaking ahead of Saturday's away game against Watford.
He confirmed that the two will be Arsenal's last signings for this summer transfer window as he rejected claims that the signings were made as a reaction to fans calling out for new players.
"I'm happy when our supporters are happy," he is quoted as saying by The Guardian.
"But my job is to make the right decisions, if that is exactly similar to the contract of the players and that maintains the supporters being happy – that is even better. I focus first on making the right decisions for the club.
"We are working on the deals. We are not close enough to announce today that they will sign for us, and will we sign anybody before the end of the transfer window? I am 99% confident.
"It was a strange transfer market. 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 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!"
