Summer Targets- What Arsenal need to do to be able to challenge for the title next season

Obviously, Arsenal need to sign players to be able to move forward and be able to challenge for actual success next season. But what is success? Success isn't just finishing above Tottenham or Chelsea and finishing in the top four. Success for Arsenal would be winning the Premier League or Champions League.

And to be able to do that we need to, first of all, keep Robin Van Persie, Alex Song and Theo Walcott. All three's contracts are running out in the summer of 2013 and we need to tie them down to longer term contracts, especially Van Persie.
Second of all, we need to improve the squad, not just maintain it. In my last article, I wrote about which players I think Arsenal should sell. So the likes of Arshavin, Squillaci and Djourou need to go and we need to replace them with better players that are more likely to help the club move forward.
The positions I think we need to improve are; centre defence, left back, defensive midfield, out wide and up front. That's quite a lot of positions, but I'm talking squad- wise. If we improve at the right standard in these positions we have a good chance of winning the league. Improving 2 or 3 of these positions will maybe see us challenge for the title, but fall short and finish around 3rd.

I still think Wenger has to go if Arsenal are to move forward. The same flaws exist at the club season after season, Wenger's flaws. His mentalities aren't always good enough to win the league (e.g. his over- attacking mentality holds us back, as well as his usually poor defensive acquisitions and poor defensive tactics), he refuses to adapt to difficult situations in games and he continues to mess up in the transfer market.

But that's another issue. I think if we signed the likes of Jan Vertonghen, Yann M'Vila, Lukas Podolski, Saloman Kalou and another striker, we'd have a very good squad capable of being able to win the league and, dare I say it, the Champions League.

Of course it's easier said than done, but this would be a great squad for next season, hyperthetically:

GK's: Szczesny, Fabianski, Mannone

Defenders: Sagna, Jenkinson, Koscielny, Vermaelen, Mertesacker, Vertonghen, Gibbs, Santos

Midfielders: Song, M'Vila, Wilshere, Ramsey, Arteta, Rosicky, Frimpong, Coquelin

Wingers: Walcott, Chamberlain, Gervinho, Kalou, Miyachi

Strikers: Van Persie, Llorente, Podolski, Vela

Like I said, it's easy just to say names, but I'm just being hyperthetical. Players of this calibre in these positions will significantly improve our squad. I don't know if Llorente would be available at all, and if he is I don't know if it would be for a reasonable price, but the likes of Roberto Soldado and Olivier Giroud would also possibly be very good signings.

The point is, this is what Arsenal need to do to achieve real success next season.
