UEFA Elite Club Injury Study – 2016/17 mid-season report
2016/17 MID-SEASON REPORT
Each season, on behalf of UEFA, the Football Research Group (FRG) provides clubs
participating in the UEFA Elite Club Injury Study with reports containing up-to-date
results in the course of the year. In these reports, data is presented for each team and
compared with averages for all participating teams.
Participating clubs
This mid-season report contains results from July to December of the 2016/17 season
for the 35 clubs that provided complete data for at least five months. The following
teams have been included: AC Milan, Arsenal FC, AS Roma, Athletic Club, Bayer 04
Leverkusen, Borussia Dortmund, Chelsea FC, Club Atlético de Madrid, Club Brugge
KV, FC Barcelona, FC Basel 1893, FC København, FC Porto, FC Shakhtar Donetsk, FC
Zenit, Galatasaray AŞ, GNK Dinamo Zagreb, Juventus, Leicester City FC, LOSC Lille,
Manchester City FC, Manchester United FC, NK Maribor, Olympique Lyonnais, Paris
Saint-Germain, PFC CSKA Moskva, PFC Ludogorets Razgrad, PSV Eindhoven, Real
Madrid CF, RSC Anderlecht, SL Benfica, Southampton FC, Sporting Clube de Portugal,
SSC Napoli, Tottenham Hotspur FC.
Interpretation of results
When comparing your club’s results with those of other participating clubs, please
bear the following in mind:
Because of the limited amounts of data collected, the injury rates presented
are sometimes based on just a few actual injuries. This means that some results
should be interpreted with caution.
The overall number of injuries varies between clubs, mainly because of the
number of minor injuries. It is therefore important to look not only at the
overall injury rate, but also at the data on severe injuries and squad availability,
as these variables may have a greater impact on the club.
Only months where full data has been provided are included in this analysis.
The number of months of data may therefore differ between teams, and this
may influence the injury statistics in the report.
We hope that you will find this report useful in your daily work treating and
preventing injuries at your club. Please do not hesitate to contact FRG if you have any
questions about how to interpret the results.

Exposure
In total, 154 000 hours of exposure were recorded in the first half of the 2016/17
season, with approximately 133 000 training hours (86%) and 21 000 match hours
(14%). The average squad size has been 27 players/team.
SSC Napoli reported 5 330 hours of total exposure, with 4 804 training hours (90%)
and 527 match hours 10%).
On average, teams reported 127 training sessions and 32 matches over the review
period. Since the reporting period differed between teams, we have also calculated a
monthly training and match load. On average, teams had 21 training sessions and 5.4
matches each month, giving an average training-to-match exposure ratio of 6.4 hours
of training for each hour of match play.

Squad attendance/availability
All data in the charts in this section is in the form of percentages.
Squad attendance/availability refers to the average percentage of players who
participated in training sessions or were available for match selection over the review
period. An attendance/availability rate of 100% would mean that no player was
absent because of injury, illness, international duty or any other reason.
