Arsenal manager Arsene Wenger has hinted that the club's spending is not over during the current transfer window.
The Gunners brought in Sead Kolasinac on a free transfer before parting with a club-record fee to sign Alexandre Lacazette from Lyon, but since the latter's arrival there has been no further action.
However, amid speculation linking Arsenal with a move for AS Monaco winger Thomas Lemar, Wenger assured fans that the club are still looking for more "top-level players" to sign this summer.
"What's next is to remain active. Not a lot [has] happened. I believe there are actually two ways to improve the team. First of all to improve the quality of what we do in training to improve the squad and improve the players we have, and secondly to bring more top-level players in," he told the club's official website.
"The difficulty is to bring top-level players in because you pay a huge amount of money for very normal players at the moment. As well, all the big clubs are chasing the same players and that provokes huge inflation. Maybe this will be the first time we [football clubs] pay over £200m, maybe over £300m with Neymar and around £200m with [Kylian] Mbappe.
"So there is a huge inflation. But we are active, we are working hard and I think we have done well with Kolasinac, we have done well with Lacazette and we are continuing to work. There's the usual acceleration in the final part of August. But I think you have always to be on alert every day, because a good opportunity might turn up. Sometimes people you are after for a long time are not available and suddenly they become available. So you have always to be on alert. That's what we do."
Arsenal will take part in the traditional season curtain-raiser when they take on Chelsea in the Community Shield next Sunday.
