It's all cherry picking.. Shakhtar in the last 18 months against italian teams (over 2 legs if possible):
- Atalanta v Shakhtar 4-2 (finished behind LaDea in their group)
- Inter v Shakhtar 5-0 (knocked out)
- Inter v Shakhtar 0-0 (finished ahead of Inter)
- Roma v Shakhtar 5-1 (knocked out)
And guess which result you used to prove your point? Cherry picking at its finest, but you can do the same for every league.. For example, just taking the best 6 teams in La Liga as of today:
- Real Madrid: defeated twice by "currently 13 points behind 1st in the Ukrainian league" Real Madrid are a bit shit too
- Barcelona: finished behind Juventus in the group stage.. Juventus > Barcelona
- Sevilla: easily knocked out by Borussia Dortmund, the same team that failed to beat Lazio twice in the group stage.. Lazio > Sevilla
- Atletico Madrid: overall a worse UCL campaign than Atalanta in terms of results and performances.. Atalanta > Atletico
- Real Sociedad: 2nd in their UEL group behind Napoli and, unlike AC Milan, battered by Manchester United .. Napoli and AC Milan > Real Sociedad
- Villarreal: in the UEL SF exactly like AS Roma. Villarreal = Roma (Villarreal have to face PL mid-table team while Roma's opponent is a PL contender that, as of now, still can win the league title)
La Liga is shit as much as Serie A then, or it's just cherry picking?
The only relevant stat is the UEFA country ranking that correctly show how's the situation in Europe:
English Premier League is the best league, La Liga close 2nd, then Bundesliga and Serie A that are on a similar level, very far from the top 2 but much ahead France. Nothing more, nothing less..
