Marvin Keller, born on 3 July 2002 (age 24), is a Swiss goalkeeper with Young Boys. A commanding 6ft 3in (1.90m), he wears the number 1 shirt and is valued at around £3m by Transfermarkt.
His early senior grounding came at FC Wil 1900, where the 2021-22 season gave him the sort of regular football young goalkeepers tend to need more than they are usually granted. He made 30 league appearances there, a useful body of work at an age when many in his position are still waiting for scraps.
Keller has since moved on to Young Boys, where he has been part of Switzerland’s top-flight picture. In 2026-27, he has made eight Super League appearances, keeping his career moving at a steady professional level rather than through noise or sudden leaps.
His career so far is that of a developing Swiss goalkeeper who benefited from a proper early loan spell and has worked his way into senior football with Young Boys.
