They are two of ten Wolves men who’ve now departed for international duty as the UEFA Nations League continues across Europe this weekend.
Otto has been a regular fixture in the Spain youth levels, but Luis Enrique has now offered him the step up to the senior team in the place of Barcelona’s Jordi Alba.
The Spaniard could make his debut for the senior team at the Millennium Stadium on Thursday when they take on Spain in a friendly. Four days later Spain face England in the Nations League at Seville’s Estadio Benito Villamarin.
Costa is also involved in a senior international set-up for the first time and joins Rui Patricio and Ruben Neves in the Portugal squad. The trio travel to Poland on Thursday for their latest Nations League match, before taking on Scotland at Hampden Park in a friendly on Sunday.
Matt Doherty’s fine form has earned him another Republic of Ireland call up for a Nations League double header. The Irish are at home twice in four days, taking on Denmark on Saturday, before hosting Wales on Tuesday at the Aviva Stadium.
Raul Jimenez has a bit more travelling ahead of him as he heads to Mexico for a pair of international friendlies. On Thursday the striker will hope to face Costa Rica and Chile the following Tuesday.
Also, in senior action is Romain Saiss, whose Morocco side head for two Continental qualifying matches against Comoros on Friday and Monday.
Ruben Vinagre has stepped up the youth ranks with Portugal and features in the under-21 squad for the first time alongside Diogo Jota. The pair will be thrust into UEFA Under-21 qualification matches against Liechtenstein and Bosnia Herzegovina.
Finally, Morgan Gibbs-White has departed for England duty with the under-19s. The midfielder takes on Portugal in a friendly on Thursday and Macedonia the following Tuesday at St George’s Park, before returning home.
