In transfer windows you start to see certain trends.
For example, if one club sells a goalkeeper, it's likely that will have a knock-on effect on other teams and more goalkeepers will start moving around.
However this season there is one certain trend that's been noticed. A lot of players are swapping the Premier League for Serie A.
Now it may be harsh to headline the article 'Premier League flops', but when you look at the list, can you argue with it?
So let's start dissecting and looking into the transfers and the so-called flops of the Premier League.
To make it easier, we'll do it by clubs that have made signings from the English league.
They've made a permanent signing from the Premier League and an 18-month loan signing.
Permanent one sees Davide Santon swap Newcastle United for Inter, and the loan sees Jovetic arrive for just under two-years.
Would you say either were impressive in England? Probably not. Would you say Jovetic was given a fair chance? Probably not. However, you have to say they both flopped.
Santon looked okay at best for Newcastle, but there must be a reason they've allowed him to leave. Especially when it's a free transfer. Unless of course he let his contract run down and then forced a move himself, but even still, is he a major loss?
Then there is Jovetic of course. Yes, he had his injury problems and yes he was third-choice behind Sergio Aguero and Edin Dzeko, but even when he played, he never looked great.
He never looked like the player he was at Fiorentina and that's the reason he's gone back to Italy. He can be successful in that league. The style suits him. It's less physical. If he can keep fit, it will be a top signing for Roberto Mancini.
So that's Inter covered, now it's Napoli, who have signed one flop, and yes, this is a flop.
Introducing Vlad Chiriches. Probably the worst centre-back to embrace the Premier League. (Yes this includes Pascal Cygan)
The Romanian never settled, never looked solid and was just a mistake waiting to happen.
He has no Premier League highlights and frankly, Spurs must be delighted he's off their books. Not sure what Napoli saw to make them want to sign him personally.
Then there is AS Roma. Now we aren't talking about a mid-table team here, we are talking potentially second-favourites to win Serie A.
Should they be signing Premier League flops?!
They've brought in Wojciech Szczesny on loan. Possibly harsh to call him a flop considering he's played in the league for a few years and is only out on loan because of Petr Cech's arrival.
However, he certainly isn't established otherwise Arsene Wenger would have never signed Cech in the first place.
Following Szczesny was the arrival of Mohamed Salah from Chelsea. You could blame Jose Mourinho for never playing him, or you could blame Salah for making the move in the first place. Up to you.
What you can definitely do however is say that the Egyptian flopped in England. He went to Fiorentina on loan in January and looked his impressive self once again and will now probably have a great season at the Rome club.
Finally there is Edin Dzeko. The Bosnian striker, who like Jovetic, was back-up at the Etihad Stadium.
However, he never showed he was worth the £27million City paid for him and he simply didn't impress regularly enough in the Premier League (except the odd-game against Tottenham).
Simply, all the players that have joined the Serie A sides this summer from the Premier League are just flops who couldn't make it in England.
You may disagree, but there is a reason why they've been allowed to leave.
