Derby County have been nothing short of underwhelming so far this season and this could be down to numerous players underperforming.

The Rams find themselves in 13th position in the Championship, but that is only because of a recent upturn of form which has seen them go unbeaten in their last five games.

Returning players such as Chris Martin have been inspirational in that run as he has notched three goals in his last four outings, including a last minute equaliser against Leeds United and Curtis Davies has come in for the injured Richard Keogh and has been phenomenal since returning to the side.

Although Derby have had some good performers over the last few weeks, some of the players have been poor over the course of the opening 11 games and here we take a look at the three most disappointing players so far this season....

Kieran Dowell

Kieran Dowell was Phillip Cocu's first piece of business during the summer as he arrived on loan from Premier League side Everton but has failed to impress so far.

The young attacking midfielder has had no joy so far this season as he has not registered a single goal and only one assist for the Rams.

The 23-year-old has only completed 67% of his forward passes and just hasn't managed to get going, which in turn has seen him lose his place in the squad and he hasn't featured since Derby's 3-0 loss against Brentford at the end of August.

Since Jozefzoon signed for Derby from Brentford, he hasn't hit the ground running at Pride Park and this season he has been especially disappointing. As a winger, Jozefzoon is expected to put crosses in and feed his front man but the Dutchman has only managed to complete 18.2% of his crosses so far this season.

He hasn't been effective in and around goal as he currently has no goals or assists in his eight appearances so far, along with only a 20% shot accuracy.

The 28-year-old has been ineffective when on the ball and boasts only a 66.7% dribble accuracy and has struggled to beat his man and is struggling to contribute to the Rams attacking threat.

Kelle Roos

Kelle Roos took the no.1 spot during the early parts of last season as Frank Lampard favoured the Dutch goalkeeper over the experienced Scott Carson.

So far this season, Roos has averaged 1.23 goals conceded per game but what might be more worrying for Derby fans is his inability to claim crosses as he usually chooses to punch the ball, which has more chance of causing problems for the Rams as he is not securing possession and taking the pressure off of his defenders.

If Derby are to go for the play-offs again this season, they may need to give back-up goalkeeper Ben Hamer a chance to sure up the amount of goals they are conceding and give the defence more solidity behind them.
