Match preview
Switzerland reached the quarter-finals of Euro 2020, which proved to be their best-ever performance at a European Championship, and the national team will again be bidding to make an impression at Euro 2024.
A-Team reached the round of 16 at the 2022 World Cup, and they will fancy their chances of claiming a top-two finish in their Euro 2024 group, which also involves Hungary, Scotland and Germany.
Murat Yakin's side will enter the contest off the back of a 1-0 victory over Republic of Ireland in their last friendly at the end of March, and they have only lost one of their last 12 matches in all competitions.
Switzerland will tackle Austria in their final warm-up fixture on June 8 before taking on Hungary in their European Championship opener on June 15.
A-Team have won each of their four previous international fixtures against Estonia, including a 1-0 victory when the two teams last locked horns during qualification for Euro 2016.
Estonia have never qualified for the finals of a European Championship, and they have failed to win a single match in their last two qualification campaigns for the tournament.
Thomas Haberli's side are instead preparing to take part in the Baltic Cup, with the Faroe Islands their opponents in the semi-finals of the competition on June 8 ahead of a possible final against either Latvia or Lithuania on June 11.

Fabian Schar and Manuel Akanji are notable inclusions at the back, while a talented midfield includes the likes of Granit Xhaka, Remo Freuler and Xherdan Shaqiri.
Breel Embolo has scored 13 times for Switzerland and is expected to feature in the final third of the field, while Burnley's Zeki Amdouni could also be handed an attacking role on Tuesday.
As for Estonia, Henri Anier has scored an impressive 22 goals for his national side, and the 33-year-old is expected to feature in the final third of the field.

We say: Switzerland 2-0 Estonia
Switzerland are heavy favourites to triumph on Tuesday evening, and we are expecting the home side to secure the victory, but Estonia are capable of making it a tricky affair, which is what Switzerland will want as part of their preparations for the European Championship.
