In the study, we tried to analyze the effects of foreign players on Turkish Super League matches. For this purpose, in this long-term study, 1836 competition data played in 6 seasons between 2014 and 2020 was obtained from www.mackolik.com each year.
Pearson's correlation coefficient applied between 18 different variables (goal, shoot, pass, cross, corner, offside, foul, yellow card, red card, accurate shot, percentage of the precise pass, rate of accurate access on opponent's field, the difference of ball possession percentage, shot difference, pass difference, big team superiority, home team superiority) and the number of foreign players (NoFP, active foreign players in 90 min.).
In the Turkish Super League, within six seasons (2014-20), the NoFP in a match increased from 10.43 (38.06%) to 17.99 (64.26%). The increment was partially linear and statistically significant (F = 594.85) in all seasons. A positive association was found between NoFP several of passes (r = 0.219), percentage of accurate passes (r = 0.133), percentage of precise passes on the opponent's field (r = 0.139), exact pass difference between opponents (r = 0.114), and ball possession difference between opponents (r = 0.113). Fouls committed decreased with the increase of NoFP (r = -0.250). Although the win probability of the teams named The Big Three (Fenerbahçe, Galatasaray, and Beşiktaş) decreased from 67% (2014 season rate) to 50% in the last two seasons, no association was identified between the NoFP and big team superiority.
Consequently, NoFP increment may improve the game quality by increasing accurate passes and passes in the opponent's field. The number of passes and the ball possession percentage difference between opponent teams may indicate that one team has control of the game by keeping possession or the other is tactically giving possession. These findings may suggest that the game evolved into half-field, tactical, set-play, possessioning competition. Analyzing variables such as game speed, intensity, the duration of the ball in play, running distance, energy consumption, and fatigue markers may light future studies.
在本研究中，我们试图分析外籍球员对土耳其超级联赛比赛的影响。为此，在这项长期研究中，每年从www.mackolik.com获取2014年至2020年6个赛季中进行的1836场比赛数据。
对18个不同变量（进球、射门、传球、传中、角球、越位、犯规、黄牌、红牌、准确射门、精确传球百分比、在对方场地的准确进攻率、控球率差异、射门差异、传球差异、强队优势、主队优势）与外籍球员数量（NoFP，90分钟内上场的外籍球员）之间应用皮尔逊相关系数。
在土耳其超级联赛中，六个赛季（2014 - 2020年）里，一场比赛中的外籍球员数量从10.43（38.06%）增加到17.99（64.26%）。在所有赛季中，这种增加呈部分线性且具有统计学意义（F = 594.85）。发现外籍球员数量与传球次数（r = 0.219）、准确传球百分比（r = 0.133）、在对方场地的精确传球百分比（r = 0.139）、对手之间的准确传球差异（r = 0.114）以及对手之间的控球差异（r = 0.113）呈正相关。犯规次数随着外籍球员数量的增加而减少（r = -0.250）。尽管“三巨头”（费内巴切、加拉塔萨雷和贝西克塔斯）球队的获胜概率从2014赛季的67%降至最近两个赛季的50%，但未发现外籍球员数量与强队优势之间存在关联。
因此，外籍球员数量的增加可能通过增加准确传球和在对方场地的传球来提高比赛质量。对手球队之间的传球次数和控球率差异可能表明一支球队通过控球控制比赛，或者另一支球队在战术上让出控球权。这些发现可能表明比赛已演变为半场、战术性、定位球、控球型比赛。分析比赛速度、强度、球在比赛中的持续时间、跑动距离、能量消耗和疲劳指标等变量可能为未来的研究提供线索。
