The window has closed and it's believed that £870million has been spent by Premier League clubs. Leicester City are just one of the contributors spending more than £20 million, but have they spent wisely?

Who has been Leicester's best investment?

Leicester have brought in some real quality this summer, making it difficult to pinpoint exactly who their best buy is. However, Shinji Okazaki is certainly in the running. The Japanese international striker has played in every game so far scoring once in the game against West Ham United.

Okazaki is the most prolific goal scorer in Bundesliga history and Japan's third all-time top international goalscorer; consistent goals is what Leicester will need in order to make this season more comfortable than the last.

Another on the list of best buys is Switzerland midfielder and captain Gokhan Inler, from Serie A side Napoli for £5 million. Inler has a wealth of experience and quality. The 31 year-old adds to the talent Leicester already have in midfield with in form Andy King and Danny Drinkwater and other new signing N'golo Kante. 

Kante looks to be another fantastic investment. The 24 year-old has been likened to former Chelsea midfielder Claude Makelele and has already shown this season he's not a shy of a tackle or two. The French midfielder started the game against AFC Bournemouth and worked well with Jeffrey Schlupp suggesting that there's a lot more to his game than just defence.

Will experience be Leicester's saviour?

Leicester have signed some very experienced players this window, more so at the back in ex-German international Robert Huth; current Austrian international captain Christian Fuchs and Yohan Benalouane. Is it this that will keep Leicester safe?

Even if the likes of Fuchs and Benalouane doesn't play every week, the squad will benefit massively from having player as such. Young prodigies such as left-back Schlupp can take on board any advice or suggestions Fuchs may have. They will also massively bolster the quality in depth that Leicester have - something they will need if they are to achieve their target of European football in the future.

If Leicester do find themselves in aother relegation battle this season, then experience will be key - of which Leicester have plenty. The addition of three quality defenders may just give Leicester the edge over their competitors. 

The Foxes look strong out wide

If Leicester thought that they were already set out wide with the likes of Riyad Mahrez and Marc Albrighton having an exceptional start to the season, then they thought wrong. New boss Claudio Ranieri has brought in Swansea winger Nathan Dyer on a season long loan.

Dyer was the last of Ranieri's signing's this transfer window and was flown in on deadline day by helicopter. The capture of his signature gives Mahrez and Albrighton some pretty hefty competition, meaning that if they take their foot off of the gas, Leicester have a high quality player on the sidelines ready to take their place.

Overall, judging by their start to this season, Leicester's newest additions look to be incredibly beneficial. Ranieri has strengthened sufficiently without much money looking likely to have been wasted. Leicester look set to finish a whole lot better than last season, possibly even pushing for a top half finish.
