- 1st Half
And away we go...
The teams head out. Lichtsteiner leads Switzerland out, while Nani has the armband for Portugal.
And now time for the national anthems, two minutes until kick-off, or thereabouts.
Head-to-heads are few and far between with regards to Switzerland and Portugal.
They have met just once this century, with the Swiss prevailing 2-0 in the Euro 2008 group stages.
The win meant little for Switzerland, who hosted the tournament alongside Austria, as they finished bottom of the group, while Portugal topped it.
But it was at St. Jakob-Park, a good omen for the hosts.
Tonight's game will be played at St. Jakob-Park in Basel.
The stadium will ring a sorry bell for Liverpool fans, having lost 3-1 to Sevilla in the Europa League final there just four months ago.
So where's your money? The Euro champs were hardly inspiring but did enough in each game to lift the Henri Delaunay trophy. They recently beat Gibraltar 5-0 in a friendly with Nani netting a brace. Tonight's skipper will be hoping for more of the same.
Switzerland meanwhile crashed out on penalties to Poland in the last 16, and have not played since.
Can't see much between the two in truth.
No Ronaldo in the squad means Nani captains Portgual.
Andre Gomes’ injury in the 5-0 win over Gibraltar rules him out, while there is starting spot for Euro 2016 final hero, Eder.
Portugal XI vs. Switzerland: Patrício; Cédric, Pepe, Fonte, Guerreiro; Silva, Moutinho, William, Adrien; Eder, Nani.
Arsenal fans will be on Granit-watch as Xhaka starts alongside Watford’s Valon Behrami in midfield for the hosts.
Switzerland XI vs. Portugal: Sommer; Lichtsteiner, Schär, Djourou, Rodriguez; Behrami, Xhaka; Dzemaili; Mehmedi, Seferovic, Embolo.
