Arsenal manager Arsene Wenger has vowed to keep spending big this summer in an effort to win the Premier League title - provided he can secure the right players.
The Frenchman has already recruited three new signings this summer, including Swiss international Granit Xhaka for a reported free of around £30m.
As things stand, that is the biggest individual fee paid out by an English club in the close season, although Manchester United could yet break the world record to bring Paul Pogba back to Old Trafford, and Wenger is expected to add further players to his squad following last season's second-place finish.
"We are very active and if we find the right candidates, we will spend the big money," Wenger said. "We have already spent big and, until now, nobody has made a bigger transfer than we have in the country.
"Even if Pogba might fly from Italy to England, I don't know, but overall we have made a big investment already and we are active.
"I believe we are active, very are active every day, and it's not over. Today we are in July and the transfer market finishes on August 31.
"A lot happens many times in the last week so it's a long time to go but we are active, we are working."
Reports have linked Arsenal with Barcelona's Arda Turan, Lyon striker Alexandre Lacazette and Matthias Ginter of Borussia Dortmund.
Mauro Icardi, who said this week he was pledging his future to current club Inter Milan, has also been linked with a switch to the Emirates.
Wenger - who has refused to be drawn on reports he was offered the England manager's job - added: "I wouldn't like to comment on names because after, if we don't get them, people ask why."
