Despite taking the lead through Tokelo Rantie in the 14th minute against Cape Verde in Praia on Friday, Bafana were defeated 2-1 and missed out on a good chance to claim top spot in Group D.
Things fell apart for Bafana, who looked rattled when the Blue Sharks fought back with two goals before the break. The sending off of Mulomowandau Mathoho in the second half made life even more difficult for Stuart Baxter’s men.
Burkina Faso top the group with five points after their goalless draw with Senegal in Dakar on Saturday. It was a good result away from home for the Burkinabe, who will go into the final three matches in the campaign desperate to stay at the summit and qualify for their first ever World Cup.
With two home matches left, including the one against Cape Verde at Moses Mabhida Stadium on Tuesday [7pm], Bafana cannot afford to drop points going forward.
"Yeah obviously for us as a team it is extremely disappointing. We felt like, after last night's result between Senegal and Burkina Faso, that it was a big opportunity for us to make our mark in the group," said Grobler, who came on in the 52nd minute for Turkey-bound forward Lebogang Manyama.
"We missed out on the opportunity, but we got to learn from it. We had a good meeting last night [Saturday] and the guys are still in good spirits and I think we have a good opportunity now on Tuesday. It's up to us.
"We got a good enough squad and we got to go out there and win the rest of our games and that is the plan."
The SuperSport United striker did not want to make the issue of playing on astroturf an excuse for Bafana’s performance.
"It could've played a part but to be honest everyone here is professional and they’ve played on the artificial pitch many times," he said.
"So I'm not going to make an excuse. I think we could've won the game, so I'm not going to stand here and blame the pitch, not at all."
