It is just 10 days until new Nottingham Forest boss Sabri Lamouchi gets his first taste of Championship action, as his side welcome West Bromwich Albion on the opening weekend. 

Lamouchi has been busy making additions to his squad this summer, with six players having arrived at the City Ground in the window so far.

One area the Frenchman is yet to strengthen his striking unit. Lewis Grabban led the side with 17 goals last season but there have been rumblings that the 31-year-old is unhappy with at the club.

Forest legend Kenny Burns suggested in his column for the Nottingham Post that Grabban: "Just doesn't look happy in his work," and added: "If he is unhappy here, then the club should look to try and move him on before his value decreases significantly."

It was a bold claim to make by Burns but just what would the Reds be losing if they did decide to cash in? We put a spotlight on Grabban's performances last season to find out.

The 31-year-old joined Forest last summer for a reported fee of £6 million and made 39 Championship appearances in his debut season for the club. Grabban scored 16 goals, just below his 16.34 expected goals, and provided three assists – a good haul that looks all the more impressive when you consider that 10 of his appearances were off the bench.

The Englishman was a clinical goalscorer for the Reds last season, he had the third-highest shot accuracy of any Championship player, 52.2%, and scored his 16 goals in just 69 shots – half the amount of attempts of league leader Neal Maupay.

The striker averaged 3.5 touches in the opposition box per game but he took just an average of 2.2 shots per game, which would indicate he was unlikely to have an attempt unless he felt the position was favourable.

An area where the 31-year-old offered Forest very little was in the air. Grabban won just 146 aerial duels last season, an average of 4.48 per game at a lowly success rate of 17.1%.

It could be argued that with target man Daryl Murphy, who won an average of 13.9 aerial duels per game last season, also in the squad that side of his game is not needed but it could be incredibly useful in link-up play.

Given the performances of Joe Lolley, who scored 11 goals, last season and the arrival of a number of new attacking options, such as Albert Adomah and Tiago Silva, link-up play is likely to be an increasingly important part of Grabban's game in the upcoming campaign.

The striker showed he was a useful distributor in 2018/19, finishing the season with a passing accuracy of 78.8%–impressive for an out-and-out goalscorer.

Grabban's goals were vital for Forest last season, with Lolley the only other player to make it into double figures. Lamouchi's alternatives consist of a 36-year-old Murphy and the relatively untested 22-year-old Tyler Walker, so it looks as if he is set to play another important role in the upcoming campaign.

However, the 31-year-old has hardly been a settled individual in recent years. Forest is his sixth club in five years and the manner in which he made his exit from Sunderland should be a serious red flag.

Lamouchi needs to assess where the 31-year-old's head is at and whether he is happy to be at the City Ground this season. If he is happy then he should stay, but if he is already showing negative signs then the Reds boss should look to cash in and reinvest.
