After their 0-0 draw with Reading, Wigan Athletic boss Steve Bruce admits their Premiership status is anything but assured.
Wigan need two more points to secure their place in the top flight for next season but face Aston Villa away and Manchester United at home in their last two games of the campaign.
"We started well but lost some impetus after Mario went off," said Bruce. "It petered out into two nervous, anxious teams fighting for their lives.
"For both sets of players the occasion and the magnitude made them forget how to play the game but who knows - that might be the point that keeps us in the league."
He added: "I can't see Mario coming back for the remaining two games of the season and we now have to focus on those.
"We have got to go to Aston Villa next week and then Manchester United here but no one gave us a chance of getting anything at Chelsea so we will have to see what happens."
