A lack of match sharpness could hamper Enyimba of Nigeria when they tackle Rayon Sports of Rwanda in Kigali this weekend in a CAF Confederation Cup quarter-final first leg.

The Nigerian league was halted because of a national association power struggle between incumbent Amaju Pinnick and Chris Giva, which the former won.

Then, the championship was shortened by 14 rounds because of fixture congestion, leaving Enyimba short of competitive fixtures as they seek a fifth African title.

They won successive CAF Champions League titles in 2003 and 2004 and the CAF Super Cup matches that followed those triumphs.

Another worry for Enyimba is a lack of goals in Africa — they have managed only 11 in 10 outings with leading scorers Ibrahim Mustapha and Chinonso Okonkwo claiming just two each.
