Arsenal are among the busiest Premier League clubs in the summer transfer window, but their spending may not be over yet. The Gunners spent almost £150 million to step up their defence with the likes of Ramsdale and Ben White and turned Erdegaard, on loan from Real Madrid, into a permanent transfer.

After a bad start to the season, Arteta has turned the tide and led the team to a temporary fourth place, of course, the superficial beauty can not hide the existence of the problem, so he still has some problems to solve.
The biggest issue is about The future of Aubameyang, who was stripped of his captain for a breach of discipline and who hasn't been on the squad for more than a month before he returns from the Africa Cup of Nations. If the team needs a big change, which may not be solved by a transfer window, but the problem still needs to be solved, then what about Arsenal's best and worst team building?
The best lineup!!!
Based on Arsenal's performance without Aubameyang, the ideal is to sell the sheep in January. If Arsenal can handle Aubameyang, then a suitable replacement will need to be found.
Everton and England striker LeWin remain an option, while Fiorentina's Vlahovic were watched by Arsenal and other Premier League teams after rejecting a new contract.
Both Thomas and Herneny left because of the Africa Cup of Nations. So the best option in midfield should be a young, high-quality player with Premier League experience, while Lille's Renato. Sanchez fit very well. There are reports that the Lille midfielder has signed a deal with the club and he can leave after January.
So the best lineup: Ramsdale; Kenyo Fuan, Ben. White, Gabriel, Tierney; Sanchez, Xhaka, Erdegaard; Saka, Smith. Rowe, Lewin;
Worst lineup!!!
Given the number of new players added this summer, the worst-case scenario could be arsenal destroying everything they built up last season.
Coutinho is once again linked to Arsenal as Barca try to cut wage spending, but the Brazilians may end up representing everyone the Gunners think they've left. Willian's departure was a blessing for Arsenal, allowing Arsenal to work for Saka, Odegaard and Smith. Rowe, and even Martinelli found the location. So the arrival of the high-paid Coutinho could disrupt the harmony of the team.
With the American Sheep falling out of favor and the expiry of the contracts of Lacazette and Nketia, arsenal will be at risk of being laid off if Arsenal allow Lacazette and the American Sheep to leave without completing a deal and fail to find a suitable replacement.
The lack of midfield enhancement would not be the end of the world, however since Xhaka and Lokunga could be a problem, especially since Niles was allowed to go on loan.
But the biggest issue is keeping the existing starters healthy to ensure Arsenal can build a strong starting line-up while potentially transferring some of the old players.
So the worst lineups will be: Ramsdale; Kenyo Fuan, Ben. White, Gabriel, Tierney; Thomas, Lokuna, Cordinho; Saka, Smith. Rowe, Nketiah.
