It is true that Costa has impressed in his attacking role for the Blues, netting 4 times in his first three games as the Blues sit top of this embryonic Premier League.
But Sterling has arguably been even more impressive for Liverpool, especially as the Reds come to terms with the loss of former talisman Luis Suarez.
Against Tottenham Sterling was a real menace, tormenting the chasing defence and midfield, and scoring the key opening goal.
It is telling that among the many quick and skilful wingers England have had in recent years, and Tottenham have two of them in Aaron Lennon and Andros Townsend, no one has managed to take their game to a level anywhere near how the 19-year-old is already performing.
Below we look at four of the strongest attacking players so far in the division, sorted by those that have had 5 or more shots on target:
|Team||Goals||Ontarget Scoring Att||Goal Assist||Was Fouled||Touches||Passing Accuracy %||Apps||Mins|
While Costa offers purely a goalscoring threat at the tip of the Chelsea attack, Sterling impresses in a wide range of various attacking departments.
The England winger has not only netted twice, with only three other players having scored more, but has also provided an assist, and has been the victim of fouls more often than Chelsea's Spanish striker. Compared to the others above, Sterling also has a stronger passing accuracy and superb number of touches, indicating that he is a much more central figure in the matches he features in. All strong statistics considering he more than holds his own from a goalsoring/goal threat perspective.
Swansea's Wilfried Bony has interestingly failed to score from his 6 attempts, while also failing to provide any assists, while Sturridge is yet to explode into the form he demonstrated for much of last year. It would be hard to argue that Costa has been the strongest striker in the division, but Sterling sure puts up an interesting case for best overall player so far.
One thing is for sure, it won't be an easy decision for those announcing the Premier League player of the month for August
