SV Werder Bremen won its first ever German double, clinching both Bundesliga and the DFB-Pokal.
 Following a club record-breaking league season, Werder won the title six points clear of Bayern Munich, with Aílton hitting 28 goals, the most ever from a Werder Bremen player.
 The cup victory was clinched following a 3–2 win against Alemannia Aachen, with defensive midfielder Tim Borowski the unexpected hero, hitting Alemannia with a brace.
 The title successes were Thomas Schaaf's first in his managerial career.
 However, Werder lost both Aílton and defensive senior talisman Mladen Krstajić to Schalke 04, since both refused to sign new contracts with the club.

 He was prolific during wartime football, but was not offered a new contract at the end of the conflict, and went on to have a journeyman career, playing for five more clubs before retiring in 1926.
 His brother, George, was also a professional footballer.

Nils-Eric "Nisse" Johansson (born 13 January 1980) is a Swedish professional football player who currently plays as left-back for AIK.
AIK had a disappointing season, where the team did not win a single match in the wake of the sale of Brazilian star Wílton Figueiredo, dropping out of the title chase, missing European qualification in the process.
 Argentine recruits Iván Obolo and Lucas Valdemarín impressed upon their arrivals, forming an impressive unit with Figueiredo, which was curtailed when Al-Rayyan bought Figueiredo in September.
 The defense was arguably AIK's greatest asset, conceding just 28 goals, led by keeper Daniel Örlund and new talisman Nils-Eric Johansson.
Allsvenskan 1998, part of the 1998 Swedish football season, was the 74th Allsvenskan season played.
