Abraham has recently Tom Waddle Jersey been the man of the moment for the Blues with back-to-back braces against Norwich City and Sheffield United but it remains to be seen whether he can perform against the big boys.Lille Ligue 1: Comparing to the other teams in the group, Lille are probably considered as the weak link.
