Almost his entire senior football career Deglis played for Daugava Rīga, capping more than 350 appearances for the team, quite often being the only Latvian origin player on the field (thus – the Latvian rifleman). Playing with the head was known as his strong side. In 1980–1981 he tried to secure himself a position in FC Dynamo Moscow but after failing to participate in a single match for Dynamo he returned to Riga where under the management of Jānis Skredelis Daugava was climbing out of the hole where it had spent the late Seventies – early Eighties and two years in a row nearly earned a promotion to the top Soviet league.

Just when the results for Daugava were getting worse again Deglis moved to Zvejnieks Liepāja where he spent the 1987–1988 seasons. In 1989 he again was a player of Daugava,^{[citation needed][1]} then for one year he played with FC KooTeePee in Finland.
