Several Hornets are representing their nations around the world this summer.
From Ismaïla Sarr's stunning displays for Senegal to Andre Gray's first Jamaica goal and Daniel Bachmann's breakthrough with Austria, read our international round-up below to re-cap the action...
Ismaïla Sarr – Senegal
Off the back of a Player of the Season-winning campaign for Watford, Sarr carried his impressive club form over to international duty in Senegal's friendlies with Zambia and Cape Verde.
The winger was instrumental in all three goals scored by Senegal in their 3-1 win over Zambia, winning a penalty for Sadio Mané, notching an assist and then sealing the victory with a well-taken finish just before half-time.
Sarr continued to pose a threat in the subsequent 2-0 victory against Cape Verde, winning another penalty late on as Mané once again converted to score the second goal of the game.
Daniel Bachmann – Austria
Bachmann's unforgettable season has reached new heights, with the goalkeeper making his senior international debut for Austria last week.
Bachmann made several important saves against England, including an excellent stop to deny Harry Kane, and followed his debut up with a clean sheet in Austria's final Euro 2020 warm-up match with Slovakia.
The 26-year-old is now set to start Austria's first game of the tournament against North Macedonia on Sunday, with manager Franco Foda already confirming the Hornet as his No.1.
Ken Sema – Sweden
Sema will also participate in Euro 2020, in Group E with Sweden. He came off the bench in warm-up victories over Finland and Armenia, and will hope for more action when his country kick off their tournament against Spain on Monday.
Despite making his Sweden debut in 2017, Sema narrowly missed out on selection for the 2018 World Cup and this will be the 27-year-old's first taste of senior tournament action.
Andre Gray – Jamaica
Gray scored his first goal for Jamaica on Monday morning, opening the scoring in a friendly match against Serbia.
The striker, who was first called up by Jamaica and made his debut in March, beat opposition defenders for pace, caught the goalkeeper out of position and converted brilliantly from a tight angle.
Jamaica's next fixtures are in July in the CONCACAF Gold Cup.
Francisco Sierralta – Chile
Before the Copa America, which begins on Sunday in Brazil, Sierralta and his Chile teammates have been participating in CONMEBOL World Cup qualifiers.
Having remained on the bench during a draw against Argentina, Sierralta was awarded a fourth start for his country against Bolivia and played 85 minutes in a 1-1 draw which leaves La Roja seventh in their group.
Sierralta will now hope to be selected as part of MartÃn Lasarte's final 28 for the upcoming Copa America competition, where Chile will kick off their campaign against Argentina on Monday night.
Craig Cathcart – Northern Ireland
Centre-back Cathcart played every minute for Northern Ireland in their two friendly matches with Malta and Ukraine. They lost narrowly to Euro 2020-bound Ukraine, but beat Malta 3-0 at the end of May.
William Troost-Ekong – Nigeria
Troost-Ekong played 90 minutes in Nigeria's 1-0 defeat to Cameroon before the centre-back was forced off through injury.
Daniel Phillips – Trinidad and Tobago
Youngster Phillips earned another cap for Trinidad and Tobago in their 0-0 draw with the Bahamas. Phillips will also hope to be included in the squad which will face Montserrat in a play-off for the CONCACAF Gold Cup in July.
Bosun Lawal – Republic of Ireland U21s
Academy Player of the Season Lawal made his debut for the Republic of Ireland Under-21s against Denmark on Saturday, coming off the bench at half-time.
