Cosmos de Bafia will be out to upset Tunisian giants Esperance de Tunis when the two sides clash in a first round, first leg CAF Champions League tie at Stade de la Réunification in Douala on Sunday.

Kick-off is set 16h30 CAT.

The Cameroon outfit booked their place in the first round with a 3-1 aggregate win over Uganda's Kampala City Council having qualified for the Champions League after finishing as runners-up in Cameroon's Premier League last season.

The Bafia based outfit will have it all to do if they were to cause an upset and progress to the second round of the competition at the expense of the 2013/2014 Tunisian League champions.

Esperance have won Africa's premium cup competition on two occasions, claiming the continental crown in 1994 and 2011.

The Blood and Gold though have shown a touch of vulnerability this season despite suffering only a single defeat since the turn of the year.

Cosmos meanwhile sit in the relegation zone in Cameroon's Elite One League after five rounds of fixtures.

The winner of the two-legged tie will face either Angolan side Kabuscorp or Sudanese outfit Al-Merrikh for a place in the group stages of the competition.

The return leg is scheduled for the weekend of the 3-5 of April.
