Paris Saint-Germain effectively wrapped up another Ligue 1 title on Sunday as a 1-0 win over Brest left them six points clear of nearest rivals Lens with two games remaining, with Luis Enrique's side also boasting a superior goal difference.
Desire Doue was one of nine PSG players rested at kick-off following Wednesday's Champions League semifinal, second leg away to Bayern Munich, but the French international came off the bench in the second half and fired in the only goal of the game from the edge of the box in the 83rd minute.
PSG will be officially crowned French champions for the fifth season running, and the 12th time in the last 14 years, if they avoid defeat away to Lens on Wednesday.
However, even if PSG lose their last two league matches, and Lens win theirs, the latter would still have to overturn a difference of 15 goals – something which is almost certainly beyond Pierre Sage's team.
Luis Enrique's side are also preparing for the Champions League final against Arsenal later this month after edging Bayern 6-5 on aggregate in their semifinal.
