Sporting CP hierarchy is growing increasingly anxious over manager Rui Borges ahead of Friday's away trip to Braga following consecutive league draws with Arouca and Famalicao.
According to a report by Portuguese newspaper Correio da Manha, another slip up against Braga, whether a draw or a defeat, could leave Sporting eight or nine points off top spot.
That prospective gap depends on league leaders FC Porto securing a victory against Maritimo in their own match, a scenario that would leave Sporting's title ambitions severely compromised at an early stage of the championship.
Pressure on Rui Borges
The manager finds himself in a delicate position after recent points dropped in drawn matches against Arouca and Famalicao put pressure on the Lisbon club's technical staff.
Sporting face a difficult task on Friday, having failed to win in their past six visits to Braga's home ground.
Rui Borges has also never recorded a victory at Braga during his tenure as manager of Sporting, adding to the apprehension within the club's board.

Title Race Implications
Correio da Manha reporter Nuno Fernandes noted that decision makers at Sporting view the upcoming fixture as a critical moment in their season.
A failure to collect three points in Braga would allow FC Porto to extend their lead significantly if Porto defeat Maritimo.
Club leaders fear that an eight or nine point deficit so early in the campaign would make catching the leaders extremely difficult.
Portuguese Football Context
Sporting CP are one of the traditional powerhouse clubs in Portuguese football, competing at the top level of the Primeira Liga alongside rivals such as FC Porto.
Braga have consistently established themselves as one of the most challenging away destinations in Portugal for visiting teams.
FC Porto remain one of Sporting's primary competitors for national honours in Portuguese domestic football.
