Sources within the club have said Swallows’ failure to win any of their past seven matches may spell the end for the embattled Marques.
The Dube Birds have fallen out of the top eight and as things stand, it does not look like their woes may end soon.
“Zeca has been told to get things right before it’s too late,” a source said.
“We have not only dropped points, but our form has dipped.”
Swallows lost 1-0 to Orlando Pirates in a PSL encounter at home in midweek.
After the game at Dobsonville Stadium, Marques confidently declared it was their last loss given their spirited display after the interval.
Today, as they travel to Mpumalanga’s Kanyamazane Stadium, Marques is expected to end a series of bad results which has seen his side drop to 12th spot in the Absa Premiership standings.
The source said the Dube Birds’ hierarchy are yet to shortlist possible candidates for the job should Marques fail to stop the rot.
“We do not know yet who might come at this stage of the season,” the source said.
“Things have been so bad that we might be fighting relegation.”
Swallows could have an uphill battle today as they will face formidable opponents in Aces, who won at Golden Arrows on Wednesday night.
Clive Barker’s side have blown hot and cold this season, but one thing they seem to be guaranteed of is Premiership status next season. They are 10th on the standings with 27 points.
Suspended striker Mabhuti Khenyeza has been their talisman this season and he started his six-match ban when they played Arrows, but Amazayoni were still able to win.
Khenyeza was handed the suspension following his long case with the PSL for spitting at a match official last season while still an Ajax Cape Town player.
This afternoon, Aces will be out to prove they can continue on their winning ways without Khenyeza at the expense of a wounded Swallows.
The match starts at 3.30pm.
