Bet365 has Turkey at 10/3, and Netherlands at 3/4. It is really surprising. I would not agree with these odds. The gambling sites are under-estimating Turkey. A good strategy would be to place two bets on this match. One for a win by Turkey (10/3, i.e 4.33) and the second one for draw (14/5 or 3.80). I believe that there is a very high chance for either of these two outcomes. BTW, France vs Ukraine also looks interesting.
Yes, for some reason bookmakers greatly overestimate the chances of some teams... In addition to Turkey, I would also highlight the match Spain vs Greece... Spain is certainly a strong opponent, but Greece also plays good soccer! They were even European champions in 2004... Damn, how long ago it was!

In general, I think the Greeks are a strong team too...
