For being capable of playing there, the players need to combine football skills and quality with sharpness and strength, mental and physical. One of the players with great reputation and career in the Italian league is the Belgian Radja Nainggolan.

The FX-Ray Project will proceed to a deep analysis, focusing on the individual statistical profile of the player. Therefore, the best seasons of his career, so far, and what should the football fans expect from him to perform in the upcoming season can be elaborated.

Data Collection, Analysis and Methodology

For the purpose of the research, individual data from certain categories will be collected since the first full season of Radja Nainggolan in Cagliari Calcio, back in 2011. All competitions, in which the player participated, are taken into account, except from those with his national team. The stats will be analyzed in two different parts, based on the offensive and defensive contribution of the player.

Moreover, positive and negative weights will be introduced to the data, by producing a certain score for each one of the statistical categories for both offense and defense. The total score will be representative of the Belgian’s performance for every single season.

Results & Discussion

Part I

Offensive Performance

Nainggonal is an attacking midfielder with many offensive assets. From his very first season in the starting squad of Cagliari, he managed to show a lot of those on the field. He avoids to make unnecessary dribbles with the ball but, when he is obligated to dribble, he makes it in top level. Notwithstanding, he commits unsuccessful touches more often than before, which is normal considering the initiatives and the duties he has taken on, throughout the years. Since his transfer to Roma, in January 2014, he has proven that his improvement is essential.

Under no circumstances can the Belgian be thought as a scoring machine. His game style is based on the creation of scoring opportunities for his teammates. Of course, there were seasons in which he was more efficient in goals than in assists, or the opposite. Only during season 2016-17 can someone claim that he combined score with chances creation sufficiently.

By taking into account all the offensive stats that illustrate the overall offensive performance of Nainggolan, the insertion of positive weights in goals, assists, shots, key passes and successful dribbles will proceed. On the other hand, negative weights will be inserted in unsuccessful dribbles, unsuccessful touches and dispossession. Then, the score of the offensive performance of Nainggolan per season will be extracted.

According to the score table, his offensive performance was extremely improved since his transfer to Roma and after. During the last two seasons, in which Roma almost reached the Serie A title and the Champions League final, his offensive performance met high standards.

Part II

Defensive Performance

Radja Nainggolan might be a charismatic player with major offensive features, but that does not seem to be verified when his team needs from him to defend. More precisely, he receives too many cards for his position, while he is being less and less implicated with the defensive part of the game. By observing his defensive behavior, it is confirmed that all his stats encounter significant drop from 2014 and after. His only defensive feature that has been improved is the frequency the opponents dribble him successfully.

For reaching the defensive scores for each season, it is necessary to follow the same procedure as in the offensive stats. This time, positive weights will be introduced in interceptions, tackles and aerial duels won and negative ones in aerial duels lost, dribbles suffered and cards (yellow – red).

The scores, resulted from the weights’ insertion, reveal the best season of the Belgian, defensively. According to the score table, after the departure from Cagliari, his defensive performance has excessively been decreased. In fact, his stats are getting poorer and poorer, by showing incapability of performing in high standards, defensively.

Concerning the final score table, during season 2016-17, Nainggolan reached the peak of his individual performance, followed by season 2017-18. In other words, over the last two years, he performs as a top-class player, leading his club close to inconceivable achievements.

II. Use of Forecasting Model

By using the Forecasting Model, the range between the Lower and the Upper Bound of Radja Nainggolan score for season 2018-19 can be predicted. The confidence level will be 95%.

Through the forecasting technique, using linear approach, the average score of Nainggolan for 2019 is 10.00, with a Lower Bound of 7.24 and an Upper Bound of 12.77. That means that he is expected to perform better than the previous season in Roma, or at least in similar standards. In the best-case scenario, for the current season he is expected to surpass the level of performance of 2016-17, the best in his career individually.

III. Scoring and Passing Contribution

Although his indisputable quality in offense, Nainggolan could not leave his mark on the offensive game of Cagliari. This can be explained by the fact that Cagliari was small-sized club which was trying to avoid relegation. The team’s quality was one of the main reasons for this situation. With Roma’s kit, his contribution was inexplicably greater.

At the three and a half seasons in Cagliari, the scoring contribution of Nainggolan was 13 goals (7 goals, 6 assists). At the same period, his club scored 167 goals, which means that the actual contribution of Nainggolan was almost 8%.

Additionally, during his four and half seasons for Roma, the corresponding contribution was again 62 goals. Despite the change in the competition level, the Belgian scored (33 goals) and assisting more (29 assists) than his regular standards. The goals of Roma were 431, which means that the contribution of Nainggolan almost reached 14.5%.

For the end, the individual passing performance of the player is presented. As it is perceived, Nainggolan possesses incredible passing skills. In eight seasons in Italy, he never had less than 80% in passes per match. The fact that his average passes per game have recently dropped is associated with his preference to dribble more often.
