The fullback has cemented his place as the Gunners' first choice right back over the last few months.
The 20-year-old only made his first start for the club last September when he was involved in a Champions League tie against Borussia Dortmund, and since then has gone from strength to strength as a first team player at the Emirates.
Bellerin ended up with 28 appearances to his name last season, which also saw him win his first Under-21 cap for Spain, but his opportunities originally came about because of injuries to Mathieu Debuchy, and elsewhere in defence that saw Calum Chambers deputising in the middle of the defence.
However, in the early games of this campaign, Bellerin has proved that he is the first choice option at fullback for Arsene Wenger, and this has been enough for Vincente Del Bosque to call him up to represent his country.
Bellerin will of course be joined by fellow Arsenal man Santi Cazorla, and will have plenty of competition at fullback with Cesar Azpilicueta, Juanfran and Dani Carvajal all selected in the latest squad as well.
Though Del Bosque may just be eager to take a look at the former Barcelona youth player before utilising him in games further down the line, just looking at how quickly Bellerin seized the attention of Wenger at Arsenal may indicate that the youngster is fully capable of taking coaches by surprise with his quality.
