Portugal v Switzerland (Estádio do Dragão, 1945 BST, Sky Sports Main Event)

The first of the UEFA Nations League semi-finals takes place in Porto, where Portugal take on outsiders Switzerland.

The current European champions are favourites with some bookmakers to win the tournament outright, but there is some value in backing their opponents to reach the final.

The hosts have been held back by draws in recent games. No defeat in four looks good on the records, but the fact all have ended level potentially shows the issue they have.

On the contrary, Switzerland saw two of their four group games end with them scoring five or more goals. The most eye-catching result being that convincing 5-2 hammering of World Cup semi-finalists Belgium, a game where they found themselves 2-0 down early on.
