Jonas scored a late winner as Portuguese champions Benfica came from behind to beat Moreirense 3-2 in their Primeira Liga clash at the Estadio da Luz.
The Portuguese champions slipped behind in the 29th minute when Rafael Martins was played through by Vitor Gomes, before sliding a low effort into the far corner.
It took Benfica until the 75th minute to draw level, as Raul Jimenez got in front of his marker to power in a firm header.
Within the space of a minute the hosts were ahead as Andreas Samaris fired a powerful strike beyond the reach of the keeper and into the top corner.
The visitors hit back and they levelled the scores eight minutes later when Ramon Cardozo slotted in from Emmanuel Boateng's pass, despite appearing to be in an offside position.
However, just two minutes later Jonas was picked out inside the box by Nicolas Gaitan, before crashing in a volley to finally seal the points for Benfica.
