I'm an Arsenal fan, and to be quite honest I agree that we will not win the Premier League. As much as it's wishful thinking to think we will, everything points towards we won't.
Although it's a big deal that Fabregas is gone, I have confidence that Ramsey and Wilshere can fill the void. Maybe not to the extent Fabregas could when he was fit, but they've proven during the Pre-season that they can work together very well. Combine them with Song and/or Frimpong (who has impressed and can fill Song's shoes just fine) and our Centre Midfield should be fine. I know that it's not of a high quality due to Ramsey being only 20 and Wilshere being 19, but they can get the job done. I think many jump the gun and shoot down our chances due to Fabregas and Nasri leaving, but I feel their departures only lower our chances a little bit.
Speaking of Nasri leaving, I feel as if his void can be filled easily. He only had one good season with us, just one, and now he thinks he deserves a massive salary and trophies. I truly hope he falls victim to Man City's massive squad and struggles to get game time, because only then will he realise what a big mistake he has made. We primarily used him on the left, but Gervinho has come into the squad and has impressed hugely, and I personally feel he'll have a great season. Obviously it hasn't gone to plan due to Joey Barton being an absolute fucking tool, but it's the very first game of the season. Gervinho will be in the thick of our attack for the entire season and Nasri's imminent departure won't be missed.
I'm a little worried about our defence. Wenger has too much faith in Squillaci and even Djourou for my liking, even the commentators seem to comment on Djourou and rate him higher than Koscielny last year in many matches. I think Vermaelen is easily our best Centre back, but Koscielny is definitely second, no doubt about it. We need to use the Fabregas and the Nasri money we will likely soon get to up our bid for Phil Jagielka and actually bid for Gary Cahill and/or Chris Samba. All three have proven themselves as consistent performers in the Premier League, so now that Wenger has even more money, he has no excuse not to spend big. He'll probably look for a replacement for Fabregas and/or Nasri, and I don't have a problem with that as long as he spends on his defence first.
I believe we can finish in the top 4, but at the moment the best we can hope for is 3rd as the two Manchester teams are leading the race at the beginning of the season. Our season likely relies on who Wenger brings in in the next 15 days, and hopefully none of them are "bargain buys" rather proven players that we know can hang with the best.
