The reigning champions could only muster two home draws from their opening pair of games whilst the Swiss were stunned by Denmark despite leading 3-0
The first matches of Euro 2020 qualification are done and dusted and although many favourites won comfortably, there is still lots of potential in three of the 10 groups.
Group B saw Portugal start out as 8/13 (1.62) market leaders to gain automatic entry into the tournament next year, despite some potentially tricky ties in the form of Ukraine and Serbia.
The Euro 2016 champions hosted both sides in the last week but were only able to claim disappointing draws – causing bet365 to push them out to 11/10 (2.10) to win the group.
Ukraine needed a 93rd-minute winner in Luxembourg to see off the minnows in their first game and now sit top with four points. They are priced at 15/8 (2.88), whilst Serbia – who have played just the one game – are 11/4 (3.75).
Their involvement in the Nations League finals means that Portugal do not play in the next round of fixtures, by which time they could be as many as eight points behind Ukraine.
Group D saw a stunning match on Tuesday night as Denmark came back from 3-0 down at Switzerland to claim a draw, although they are still 5/4 (2.25) to win the group.
The Swiss - 11/10 (2.10) favourites - led comfortably but imploded with just six minutes left, conceding twice before the 90-minute mark and then once more in injury time.
Republic of Ireland currently top that group but made a less-than-convincing start to their campaign with a pair of 1-0 wins over rank outsiders Gibraltar and Georgia, and are 5/1 (6.0) to finish in top spot with bet365.
Elsewhere, World Cup finalists Croatia were stunned 2-1 in Hungary on Sunday but still maintain Group E favouritism at 2/5 (1.40).
Wales can be found at 3/1 (4.0) after they opened with a 1-0 win over Slovakia and face a crucial trip to Croatia next time out. Any positive result for Ryan Giggs’ men would likely see their odds cut drastically.
