Flamingos head coach, Bankole Olowookere has said it is important for his team to put in more work despite their convincing win over South Africa.
Olowookeres side defeated their hosts 3-1 at the Lucas Moripe Stadium, Pretoria on Saturday.
The result put the Flamingos in a good position to secure a place in the final qualifying round.
The gaffer, however, expect the Bantwana to make things difficult for his team in the second leg.
"We had a good result, but we need to improve on a few things for the next game, as I know South Africa is also going to improve, Olowookere was quoted by safa.net.
