LEVERKUSEN, Germany (Reuters) - Bayer Leverkusen's undefeated run to their first Bundesliga title was fully deserved and it was an honour to be part of a special day for the club, coach Xabi Alonso said on Sunday.

His team had earlier crushed Werder Bremen 5-0 to open a 16-point gap over deposed title holders Bayern Munich with five matches left in the season, securing their first trophy in 31 years amid wild celebrations from a 30,000 home crowd.
