Besides using The Football Efficiency Monitoring System for supporting decision for buying and selling players, or selecting the starting eleven, The Football Efficiency Monitoring System is also usable for supporting decision making in real time during the match for substitutes. In the match against AZ in the play offs for playing in the Europe League FC Utrecht showcased how The Football Efficiency Monitoring System would have helped making better decisions.
The first substitute was a case of substituting two players who are too similar to make a difference. Compare the two Football Efficiency charts of Hardeveld and Braafheid:
It could be that Hardeveld had an injury, yet there was no indication for an injury and his substitution during the break suggest otherwise. As the charts show, Hardeveld and Braafheid are too similar to make a difference.
Then we got two questionable substitutions. First we look at the substitution of Amrabat and Barazite. Here a player with high football efficiency is substituted with a player with a low football efficiency. This substitution is especially questionable because at the time of the substitution Ayoub, one of the other midfielders of FC Utrecht, had a much lower Football Efficiency. Here are the charts:
At the same time FC Utrecht also substituted Zivkovic for Kerk. Again substituting a player with a high Football Efficiency for a player with a low Football Efficiency. Again, Haller, another Utrecht forward, had a much lower Football Efficiency and would have been a much better substitution. Here are the charts that The Football Efficiency Monitoring System generated in real time:
It is highly likely that had the manager of FC Utrecht access to these charts that he would have made a better informed decision. This is only the first match and the second match still needs to be played at the home of FC Utrecht. We will see whether an away goal for FC Utrecht in this match would have made a difference. Of course, one cannot say whether different substitutes would have made a difference. But at least FC Utrecht would have had a better chance of scoring an away goal. Given that a ticket to the Europe League is at stake, if The Football Efficiency Monitoring System would have been used, it could have been that investment in the subscription for a whole season would have been recovered in these two matches.
