The game will be played in Portugal as part of the Club’s pre-season training camp and will take place on Saturday 22nd July at the Estadio Algarve (KO 8.30pm).
Benfica won last season’s Primeira Liga, finishing six points clear of nearest rivals Porto, and will provide a stern test for Leonid Slutsky’s side.
It means the Tigers now have four confirmed pre-season fixtures, as listed below:
Saturday 15th July: Oxford United – Estadio Da Nora, KO 6.30pm
Tuesday 18th July: Bristol Rovers – Estadio Da Nora, KO 6.30pm
Saturday 22nd July: Benfica – Estadio Algarve, KO 8.30pm
Tuesday 25th July: FC Nantes – KCOM Craven Park, KO 7.30pm
Any further fixtures will be added in due course.
