Who is the best signing of the summer transfer window?
More than £850million was spent by Premier League sides during this summer's transfer window, headed by Manchester United's mammoth outlay of over £150m.
Six clubs spent more than £50m each as the British transfer record fee for one player was smashed by Angel Di Maria. In fact, six of the top 10 spending European clubs this summer are from the Premier League, with just Real Madrid, Barcelona, Atletico Madrid and Borussia Dortmund amongst them.
So, with transfer records broken and hundreds of players on the move, who is the best signing of them all?

There were plenty of excellent signings made by mid-table clubs over the summer but there are six more high-profile deals that have grabbed most people's attention.
Arsenal's signing of Alexis Sanchez pushes them ever closer towards a genuine title challenge, Liverpool's purchase of Mario Balotelli means they may yet prosper without Luis Suarez, while Manchester United have done all they can to get back into the Champions League with the big-money captures of Angel Di Maria and Radamel Falcao.
It is Chelsea, however, that have made the best signing of all in the shape of Cesc Fabregas.
Diego Costa fits into the same category as the likes of Sanchez and Falcao in that he is a potentially fantastic signing but may struggle to maintain top form during his first season in the Premier League - but Fabregas won't have that problem having cut his teeth at Arsenal.
Furthermore, he is exactly what Chelsea have been missing, a genuine playmaker that will dictate the vast majority of games he plays in. Unsurprisingly, he has attempted more passes than any of his team-mates in all three of his appearances and already has four assists to his name.
At around £30million, you could hardly say he came cheaply, but that is only marginally more than United and Liverpool paid for Ander Herrera and Adam Lallana respectively. Neither of those players are in Fabregas' league.
The Spaniard also has his best years ahead of him at 27 and, having signed a five-year contract, can go on dominating Premier League midfields for years to come.
Both now and for the future, he is an exceptional signing.
James Marshment (@marshyleeds) - Eliaquim Mangala
As the defending champions, it's very hard to find a weakness in Manchester City's armoury.
Offensively, City scored an impressive 102 league goals last term as they marched towards a second Premier League title in three years, while glory in the Capital One Cup only added to their domestic domination.
But the one area that obviously needed addressing was the centre of their defence - and the need to find a world-class defensive partner for Vincent Kompany.
Although the club conceded less than a goal per game in the league last year, it's always been felt that a lack of a defensive colossus alongside the ever-reliable Kompany would be paramount if the club was to take the next step towards European domination.
Although commanding a reportedly eye-watering £32million fee, I believe City have finally landed that man in France centre-half Mangala, who showed during his three seasons at Porto that he was one of the continent's most effective stoppers.
In many ways, while the fee does appear quite steep, I'd argue City are getting twice the defender that David Luiz is - and he, of course, cost PSG a truly-preposterous £50million just a matter of a few weeks earlier.
Transfers fees aside, and despite the fact he's not as glamorous a name as the Radamel Falcaos or Angel Di Marias of this world, Mangala is a player that should add steel, poise and reliability to City's defence.
Where the likes of Joleon Lescott, Stefan Safic and to a slightly-lesser extent, Matija Nastasic, have failed, I believe Mangala can truly excel and prove a perfect foil for the slightly-more refined style of Kompany.
Football may be geared towards attacking styles and the creative genius of the Number 10, but the art of defending cannot be underestimated either and this is why, I believe, Mangala can be the signing of the summer.
