That article is just daft.
Alexis Sanchez is a world class player at the age of 25. He will be great for Arsenal if they keep him around and he offers them more penetration in attack than their typical playmakers do along with now Welbeck, Walcott and Chamberlain. He was a good buy, just not the buy that everyone was expecting Arsenal to make.
Luke Shaw was expensive, but with home-grown rules, his talent and professionalism taken into account it's a good buy on paper.
He already has loads of premier league experience as well.
Didier Drogba certainly is a better 2nd/3rd alternative than Torres. They upgraded their choices on the front this year, and Drogba is a beloved character both amongst the fans and their squad, and has only respect for Mourinho, so I don't expect him to bemoan his position in the squad. Money really isn't a big issue for Chelsea either with no loans and loads of valuable talents around, and their first team already settled with the exception of replacing their main central defenders.
Besides, they let Eto'o go. I'm fairly certain that Drogba ain't earning shitloads more than him.
Eliaquim Mangala is a very talented and physical central defender.
What have experts and sofa-managers said about Manchester City for some time? They needed another quality central defender. Mangala was expensive but he is very young, gives them another good option at the back and could potentially end up as one of the very best defenders in the game. Bad buy how exactly?
Rio Ferdinand to QPR is a given on the field.
But if they end up not having him as a first choice, he will give them experience during trainings and a good leading character.
All in all a most-likely bad acquirement, but he was initially a free-transfer and with a sensible wage-package he is worth the punt.
Mario Balotelli is a walking (not running) catastrophy, but for the 18 million Liverpool reportedly paid for him, at that time during the transfer-window i don't think they were completely looking in the mist. He is undoubtfully talented but mentally screwed, he still might turn it around at Anfield. But certainly one of the worst buys so far. Again, still young and could grow to be a Liverpool talisman.
I really don't know much about Emmanuel Riviere, so i won't comment on how he plays.
But for 5.5-million it's surely worth a punt on a relatively highly rated player from a league Newcastle have had decent luck with from before, who is still just 24.
Carlos Sanchez could just need some time to bed in at Villa, still at 1-5 million pounds it's really not much money to pay for someone who did well at the world cup. It's a punt, it may turn out bad and it may turn out good. Way too early to tell considering he came from Spain who plays football very different from the English style.
Ben Davies himself might do well, but the fact that Spurs paid money as well as giving Swansea Sigurdssson you can give it a claim as the worst transfer - if not for the potential of him being a decent player for Tottenham which he can grow up to be at the age of just 21. Tottenham needed another left-back and they already had Eriksen, Lamela & Holtby who can play in that role. It's not a huge loss for them to let Sigurdsson go, though it's a great gain for Swansea.
I have no idea about Brown Ideye and haven't watched him at all. Price seems steep so i'll give them that one.
The loan of Falcao is just stupidity to include. People have claimed Van Persie might not be up for it, Rooney having his off-form periods, Chicharito being useless at anything but finishing (but he has been useless at that for quite some time as well) and Welbeck being more of a "team-player" than an out and out striker - yet it's insisted that acquiering one of the best strikers in the world (first on loan to check his long-term fitness) is a bad idea? Even if the reported 15 million fee was true, you'd still have to consider that we don't know if it knocks off some of the price of the potential transfer-agreement.
Seems like they were so interested in making an article with a negative tone that they just had to spout some shit.
. Total bullshit given half the players they have on there weren't even brought in for the reasons they are slamming them for. There have been plenty of signings much worse than him.
