#1 Brighton & Hove Albion
Brighton have been, for the most part, bang-average so far this season. They've managed to pick up one win from seven, against Manchester United no less! Many have said that it was a fluke, and based on how their performances have been since then, some might be inclined to agree.
The Seagulls finished 15th in the league last season, avoiding the drop by a mere seven points. The biggest issue that Brighton have is with their form. There doesn't appear to be any consistency to their performances at all. We've seen that already this season with their 3-2 victory over giants Manchester United, which was followed by a 2-0 defeat to Watford.
One win amongst a string of defeats and draws is simply not good enough, and if they want to survive for another campaign in the Premier League, they need to step up sooner rather than later.
Another outstanding issue with Brighton is the fact that they made 12 signings over the summer, spending a ridiculous amount of money, and expecting them to slot into the side as soon as the season kicks off. Of course, this didn't happen; instead, the first team has been drastically chopped and changed each match to try and find the best side. As a result, they've lost games that they should have really won, all because they're yet to find a formation that works with their abundance of new faces.
