European champions Portugal are seeking their first win while seven teams enjoy perfect records as Euro 2020 qualifiers reach the half-way stage with six days of matches from tomorrow. 
Portugal, who have drawn their opening two games in Group B at home to Ukraine and Serbia in March, now visit Serbia on Saturday before going to Lithuania three days later. Since the last qualifiers, Portugal have shown they can win key games by capturing the inaugural Nations League played on home soil, defeating Switzerland 3-1 with a Cristiano Ronaldo hat-trick and the Netherlands 1-0 in the Nations League. 
The group though still looks tricky for the Portuguese, with leaders Ukraine looking to pull further clear by winning at Lithuania on Saturday. 
The Netherlands are meanwhile in action in one of the highlight matches when they visit Germany in Hamburg on Friday. 
The Dutch will be out to avenge a 3-2 home defeat to the Germans in Amsterdam in March and can hardly afford another slip up in Group C, where Joachim Loew’s German side has three wins out of three. 
The Germans will then travel to Belfast for a key game against Northern Ireland, who top the group with four wins out of four. 
“We will take a big step with two victories,” said Loew, who missed the last two qualifiers following hospital treatment. 
World champions France are neck and neck with Turkey and Iceland on nine points after four games in Group H and will be seeking maximum points Before home fans at the Stade de France — against Albania on Saturday and minnows Andorra three days later. 
Turkey, who defeated France 2-0 at home in June before succumbing to a 2-1 defeat in Iceland, meanwhile greet Andorra before travelling to Moldova, and Iceland entertain Moldova and are then at Albania. 
Italy have trips to Armenia and Finland after four wins out of four, with coach Roberto Mancini having to tweak his defence after both Juventus defenders Giorgio Chiellini and Mattia De Sciglio were injured last week. 
“We have been trying to build a good team,” Mancini said. “Let’s see what happens in the next eight, nine months; maybe someone will improve, but with those I have called up we already have a team.” Group F leaders Spain are another team with a perfect record after four matches ahead of Thursday’s match in Bucharest against Romania, a side they have never beaten in a World Cup or European Championship qualifier, and a home game against Faroe Islands on Sunday.
After Nations League action in June, England have had just two games in Group A but have begun well with two victories and 10 goals against Czech Republic and Montenegro. 
Gareth Southgate’s side now welcome Bulgaria to Wembley on Saturday before playing Kosovo in Southampton. “We feel that, as a team, we’re now rightly in the top 10 [of the FIFA rankings] and firmly embedded in that top 10 but, as we head into the Euros, we could beat any of those teams on any given day — and, as has been shown, they’re capable of beating us,” Southgate said.
