Portugal will look to make it to the final for the first time since their ill-fated adventure as Uefa Euro 2004 hosts, while Wales's improbable journey continues in Lyon.

The sides are meeting for the first time in a competitive game. Their only three previous meetings were friendlies, Portugal winning two to Wales's one.

Portugal beat Wales 3-2 in a 1949 friendly but lost 2-1 two years later in Cardiff. Their most recent encounter was in Chaves in June 2000, a 3-0 Portuguese victory.

Euro facts: Portugal

Portugal's last six Euro finals matches have ended in draws after 90 minutes; five at this competition, plus a 0-0 stalemate with Spain – preceding a shoot-out defeat – in the Euro 2012 semifinals.

Portugal drew 3-3 with Hungary in Group F on 22 June in their only previous outing in Lyon. It was a big night for two-goal Cristiano Ronaldo, who became the first man to score in four European Championships, and also the first to play in 17 Euro finals fixtu
Ronaldo could also become the first man to appear in three Euro semifinals and (having scored in 2004 against the Netherlands) only the third to score in more than one after Viktor Ponedelnik and Valentin Ivanov, who both struck for the Soviet Union in 1960 and 1964.

Portuguese clubs' record in seven Uefa games in Lyon is W2 D3 L2.

Portugal are competing at their sixth consecutive Euro and their seventh in total. They are in their fourth semifinal in five editions, 2008 the only recent exception.

Although this will be Portugal's fifth Euro semifinal overall, their sole victory was at home in 2004 – 2-1 against the Netherlands in Lisbon, with Ronaldo and Maniche scoring. They were beaten in 1984 (2-3 v France, aet), 2000 (1-2 v France, aet golden goal) and 2012 (0-0 v Spain, 2-4 penalties).

Portugal also lost Fifa World Cup semifinals in 1966 (1-2 v England) and 2006 (0-1 v France).

Portugal's greatest Euro feat is getting to the final of Euro 2004 on home soil, where they unexpectedly succumbed 1-0 to Greece.
