The one concern about Nottingham Forest's Britt Assombalonga's game in his career so far

Nottingham Forest's Britt Assombalonga still needs to add consistency to his game if he is to fulfil his potential.

Many eyebrows were raised when Nottingham Forest decided to part with over £5.5 million to secure the signing of Britt Assombalonga from Peterborough United this summer.

The Congolese front-man was untested and inexperienced in the second-tier, but Forest's faith in Assombalonga's ability has paid dividends.

Already the 21-year-old has begun repaying his considerable fee and looks one of the finest marksmen in the Championship.

Blessed with pace, power and a predator's instinct, Assombalonga looks like a player Forest will be able to build their team around for a lengthy amount of time.

However, if there is one concerning feature about Assombalonga it is his tendency to have a dip in performance levels around this time of year.

It is easy to forget that the front-man has only had two previous years as a professional before moving to the City Ground, but his form already is showing signs of tailing off, as it did for a portion of the campaign at Posh and Southend United previously. 

At the Shrimpers in the 2012/13 campaign, Assombalonga's form severely dipped during the second-half of the campaign as he tired from his initial efforts.

The striker, then on loan from Watford, scored 16 goals during his time in League Two, but 12 of them were scored before December and he only managed four more after that point. At Posh, things were similarly bad for part of the season.

Although Assombalonga managed to pick things up towards the latter stages of Peterborough's ultimately unsuccessful promotion push, from the back-end of September to the start of December he was off the pace.

Assombalonga managed to score just once in nine games and it has been a similar pattern at the City Ground.

After scoring eight times in his first nine games at Forest, he has scored just twice in the 10 matches proceeding that and he will need to get back to top form soon.

Although he should, this dry-spell is something Assombalonga will need to cut out of his game if he is ever to fulfil his entire potential.

There can be no doubt that Forest have picked up a future star in Assombalonga, but he still evidently needs to add consistency to his game before he can be called the finish product.
