Bayer Leverkusen coach Xabi Alonso has explained why Francis Onyeka will replace Victor Boniface for their UEFA Champions League clash with Brest. Boniface, recovering from an accident last weekend, was excluded as a precaution, with Alonso hoping to have him back for their Bundesliga match against Werder Bremen on Saturday. Onyeka, a promising German-Nigerian forward from the club’s youth ranks, has been called up in his place. Alonso expressed confidence in Onyeka but emphasized patience in his development.
