Expert dasss10 (Oleg Zhukov) has offered own prediction by corners.
Recently, just 3.5 months ago, Germany and Northern Ireland met at Euro 2016 in France, and local referee Clermont Turpin did not find a reason for even one yellow card in that match. All start matches of WC-2018 qualification (2 matches) teams played with total cards under 4.5 and Germany team played even with total cards under 3.5, moreover in these 4 matches Germany and Northern Ireland got only 3 YC for two! teams. This match will be judged by Italian Tagliavento. In the season 15/16 and 16/17 he judged 7 official international matches, and only 1 time used more than 4 YC, and on average it was 3.8 cards. Since 2011 he judged 9 qualification matches, 8 of them finished with total cards under 4.5, at an average total cards was 2.4.
Martin Strёmbergsson from Sweden was appointed to the match Slovakia - Scotland. Martin is like Bikardi Garrido from European football :). Over the last 3 seasons he judged 14 international and Euro cups matches, and never gave more than 5 yellow cards. And here he will have the Scotland national team, who for the 2 qualifying cycle (12 games) played on the Total cards over 5.5 only 1 time. This happened when the Serbian Mažić showed 6 YC in the Scotland and Ireland battle. All other games - with total cards under 5.5 and average YC Total 3,17 per match.
See screenshots below.
So, combo bet is:
11/10/16 21:45 Qualifiers for the World Cup. Europe. Germany - Northern Ireland. Yellow card. Total under 4.5 (odd 1.48)
11/10/16 21:45 Qualifiers for the World Cup. Europe. Slovakia - Scotland. Yellow card. Total under 5.5 (odd 1.37)
Good Luck!
