A number of summer signings have come into their respective clubs and flourished in the Premier League. However, that has not been the case for every new player and some have failed to find their feet or live up to expectations.
Here are seven of those poor performing individuals...
7. Mauro Zarate
Mauro Zarate was brought to West Ham this summer by the chairmen, not manager Sam Allardyce.
Subsequently, the forward has struggled to get game time and has only scored one goal this season, although it was a fantastic one.
Against Hull, Zarate was selfish and over-confident, attempting to take on every player who came near him instead of passing to an open man.
Injury has also meant that Zarate has failed to shine for the Hammers just yet, but he will need to compete with the high-flying Diafra Sakho and Enner Valencia if he wants minutes on the field.
6. Eliaquim Mangala
When you spend £32m on a defender, you expect him to settle into life at his new club immediately. That has not been the case for highly-rated Eliaquim Mangala.
He did have a solid game against Chelsea, despite Pablo Zabaleta being sent off, but his own goal and conceding of a penalty against Hull is not what City fans would have expected.
He went on to struggle against West Ham, with the East London side specifically targeting him as a weak-link. Mangala has a lot of work to do if he is to live up to his hefty price-tag.
5. Radamel Falcao
Falcao hasn't been awful compared to some players on this list, but that is why he is featured rather far down it. The problem Falcao faced is the huge hype around his move, followed by him simply not living up to it.
The injury-prone striker has netted just once since his arrival in the summer and United have reportedly agreed a £40m transfer deal at the end of the season, which is surprising considering his lowly contribution so far.
4. Rio Ferdinand
The most surprising thing about Rio Ferdinand's failure to find his feet in the opening 10 games of the Premier League is the fact that he has done it all before. 18 years ago.
Rio has looked slow, shaky and well past his sell-by-date for Queens Park Rangers and to make matters worse, he has been hit with a ban for a foolish comment on Twitter.
3. Ben Davies
Ben Davies has struggled in his first few games as a Spurs player, there is no denying that. What makes things worse is the fact that the North London club forked out £8m AND Gylfi Sigurdsson for the defender.
On top of that, Sigurdsson has been fantastic for Swansea yet again, whereas Davies has struggled to fit into an inconsistent Tottenham side.
2. Remy Cabella
Remy Cabella has recently stated that his manager was right to drop him following a dreadful start to his Newcastle career, so at least he's not as stupid as he is overrated.
The Frenchman is yet to score for his new club and instead has gained attention for his below-par performances and rather hilarious haircuts.
1. Mario Balotelli
No one will be surprised to see Mario Balotelli on this list, and many would have guessed he would top it.
The Italian has been laughable this season and not only has he struggled to find the net, but he has missed a wealth of simple chances along the way.
Balotelli's work rate leaves a lot to be desired and it seems Brendan Rodgers panic-bought somewhat, by signing the biggest name available to him. The only problem is that Balotelli is not necessarily known for his footballing ability and won't ever be unless he drastically improves at Liverpool.
