For informative and insightful analyses, I suggest visiting The Third Team website. It is a great website looking at refereeing from Europe. They also have some dedicated and passionate "blog observers" who produce useful and helpful assessment reports.
My observation here is just a comment on the consistency of knowledge amongst all the upcoming referees from Europe. The natural assumption is that all FIFA referees are familiar with the LOTG—especially with the interpretations—and with special guidelines or directives that arise from time to time.
On this basis, it is puzzling to see the positioning of Referee Matej Jug (Slovenia) during penalty kicks. The following incidents occurred during the 2013 UEFA U21 Final between Italy and Spain on Tuesday 18 June 2013. The match finished 2—4, with 7 YCs.
In the 37', Referee Jug is perfectly positioned to make the correct call. Here are the freeze frames:
Notice the Italian players surrounding and hounding the Referee
Look at Referee Jug's positioning
In the 64', Referee Jug is far behind from play as an Italy defender trips the Spain attacker. Here are the freeze frames:
similar "whistle in mouth" case here). Something else (not a second whistle) dangles on the other end. What is it? It looks like a dog tag or key fob.
Again, notice the Referee's positioning
Referee Matej Jug (Slovenia) and his colleagues who officiated at these U21 Championships are the next generation of top FIFA referees from Europe. They are currently categorized as Elite Development FIFA referees. The fact that there are still obvious inconsistencies with the interpretation of the LOTG should raise some concern. All match officials at international level should have sufficient training and knowledge to be consistently correct in the basic positioning concepts as described in the LOTG.
I can perhaps excuse the blatant performance of older match officials who stubbornly refuse to change their ways even in the face of the most up-to-date FIFA guidelines. The example here would be the stubborn and slovenly AR Arhar who previously worked with up-and-coming Slovenian Referee Damir Skomina (example here).
However, for Elite Development FIFA Referees, there can be no excuse for any inconsistencies with regard to the standard interpretations of the LOTG. If this basic procedure (i.e. positioning for a penalty kick) cannot be followed consistently amongst all FIFA referees, then what does it say about the referee assessors and instructors of the next generation of top FIFA referees? This blog has previously mentioned consistency problems amongst the next generation of referees (see here).
