Vega began his professional career in with local Grasshopper Club Zürich in 1989, being a defensive mainstay from his second season onwards. He was essential in two of the three leagues he actually conquered, playing in 67 games combined and scoring seven goals.
In the 1996 summer Vega moved to Italy with Cagliari Calcio, in the Serie A. However, after only seven months, he signed with England's Tottenham Hotspur, for a transfer fee of £3.75 million. He was used mostly as a backup with his new side, helping it win the Football League Cup in 1999; in the final, a 1–0 win over Leicester City, he broke his ankle, and could never regain his previous form with the Spurs.
In mid-December 2000, Vega moved on loan to Celtic – in the previous off-season, he rejected a move to the club– where he played a significant part in the winning of three trophies, in a short six-month spell. In his debut, on the 17th, he netted twice in the home demolition of Aberdeen (6–0); he also scored a brace against Dunfermline in the Scottish Cup.
Released by Tottenham in June 2001, after also having refused the Scottish club's offer of an additional year, Vega moved back to England with Watford, penning a three-year deal with the Championship outfit. One of the side's best-paid players under manager Gianluca Vialli, he was released after just one season, as the club underachieved for a final 14th position; for the Hornets he netted three times, once in the league against Norwich City and twice in the League Cup, against Bristol City and Bradford City.
Two years later, he was picked – and started – for the squad at UEFA Euro 1996 in England, helping to a 1–1 draw against the hosts. His career brought him a total of 23 caps, and he also captained the side on occasion, scoring in the 1–1 friendly match with England – who were preparing for the 1998 World Cup – in Bern.
