Arsenal have only played three games of the Premier League season, but manager Arsene Wenger is already under pressure after two successive losses.
Losing 4-0 away to Liverpool on Sunday, the side's defensive frailties were on show again, as the back-three of Rob Holding, Laurent Koscielny and Nacho Monreal failed to cope with Liverpool's pace.
This summer, Arsenal only signed two players (Alexandre Lacazette and Sead Kolasinac), but saw a number of defensive players leave on loan or permanently.
One player who left to return to Spain was Gabriel Paulista. The Brazilian joined Valencia on a five-year-deal, after a two-and-a-half year spell in London.
Speaking on Sunday's Match of the Day 2, former Arsenal defender Martin Keown could not understand the reasoning behind the decision.
Some of the rationale for the decisions today - I'm scratching my head.
Gabriel is an outstanding - probably the best pound-for-pound defender at the football club. He's been allowed to leave for £9milion. Mustafi is sitting on the bench. They paid 35 for [him].
I'm not sure now about some of the decisions that are being made.
Arsenal have less than four days left until the Transfer Window shuts. As what seems to be the case with the club each year, defensive reinforcements are needed.
Keown won three Premier Leagues and three FA Cups under Wenger at Arsenal. He has previously been seen as a fan of Arsene Wenger, but it has not taken long for him to point the blame for inept dealings in the transfer market.
It's looking ominous.
