A full international between 1994 and 2002, Blomqvist won 30 caps for the Sweden national team and helped them to third place at the 1994 FIFA World Cup in the United States.

[4] Furthermore, he played a part in the Sweden advance to the semi-finals of the World Cup and scored in the club's 3–1 win over Manchester United in the Champions League.

[5] This performance caught the eye of United manager Alex Ferguson and helped the team qualify for the quarter-finals of the tournament.

[7] The defending champions had an equally disappointing season, finishing eleventh in Serie A and failing to qualify for European football.

The Swede's sole league goal for the club was scored in a 4–0 win over Napoli at Stadio San Paolo.

[11] Due to a serious knee injury suffered soon after the Champions League final, Blomqvist did not play football in the next two seasons, which resulted in Manchester United deciding not to renew his contract (During his time out, due to this injury, he did media work for MUTV, United's in-house television channel, and presented his own cookery show called "Cooking With Jesper").

He remained on a week-to-week deal at Old Trafford before finally leaving when Ferguson persuaded Everton manager Walter Smith to offer the Swedish international a short term contract at Goodison Park, from November 2001 until the end of the season.

[12] Blomqvist played on the wings opposite compatriot Niclas Alexandersson, and scored his first goal for Everton against Sunderland in January 2002.

His spell at The Valley was even briefer, and he made just three league appearances for the South London side before calling time on an injury-hit five seasons in England.

[10] Blomqvist joined Enköping as a coach in 2008 and went on to make a playing return in the Superettan, the second tier of Swedish football.

[18] In total, he made ten Superettan appearances, but was unable to save Enköping from relegation to Division 1 for the 2009 season.

He left Enköping after the season and later signed a contract with newly relegated Hammarby as assistant manager to Michael Borgqvist.

[23] His only World Cup match in the starting eleven came against Cameroon, although he also replaced Henrik Larsson in the second half of a draw against eventual champions Brazil.
