Charlton Athletic looked to strengthen their squad substantially during the summer transfer window, after tasting promotion to the Championship, with Addicks boss Lee Bowyer bringing in a total of fourteen new additions to the Valley. 

In addition to the players arriving in south London, Bowyer also had to deal with the departures of several of his key players from the last campaign.

The likes of Joe Aribo and Krystian Bielik moving onto both Glasgow Rangers and Derby County respectively, whilst their play-off final hero Patrick Bauer moved to fellow Championship side Preston North End.

Despite these key departures, Bowyer was able to keep hold of star man Lyle Taylor who has played a major role in Charlton's lightening start to their campaign, with the Addicks currently sitting in tenth place after picking up five wins and three draws in their opening eleven Championship outings.

However, despite bringing in a host of new faces to the club, a few have yet to make an impact at the Valley, and as such we have picked out TWO Charlton signings who have failed to hit the ground running so far....

Erhun Oztumer

One player who has made an underwhelming start to life at Charlton is Turkish attacking midfielder Erhun Oztumer, who arrived at the Valley on a free transfer from League One club Bolton Wanderers this summer.

The 28-year-old former Walsall playmaker has so far been yet to make an impact in the Championship, appearing in three Championship outings but so far failing to register either a goal or an assist this term, which could be put down to Oztumer only averaging 0.7 shots and just 30 passes per game.

Lee Bowyer will certainly be expecting to see an improvement in form from the player the coming months, with the pint-sized midfielder having joined the club with a big reputation for providing a difference in games.

Tomer Hemed

One other player who has also failed to set the world alight since joining the Addicks is Israeli striker Tomer Hemed, who arrived in south London on a free transfer this summer after leaving Brighton at the end of last season.

Hemed has so far failed to find the back of the net in his first four outings for the Addicks, putting in poor displays which will not bode well with his new manger, with Bowyer having bought the 32-year-old in to fill the goalscoring void left by Lyle Taylor's injury.

With competition high for places up front in Bowyer's starting eleven, Hemed will need to perform a quick turnaround in form to guarantee a starting spot this season, with the likes of Macauley Bonne and Jonathan Leko showing good form of late.
