Arsenal manager Unai Emery took the positives from his side's 3-1 defeat to Liverpool, and was particularly pleased with one player's impact.
The Gunners had some good opportunities to score in the first half after managing to soak up some heavy pressure. Unfortunately, Emery's side conceded from a corner on the stroke of half-time.
Matip scored the first before Mohamed Salah's quickfire double at the beginning of the second half gave the Reds a commanding lead.
But Emery praised the way his side never gave up and 'kept pushing' despite going 3-0 down, with Lucas Torreira scoring a consolation goal to make the scoreline more respectable.
"We did defend deep but it was not without the possibility to score," said Emery, as per Sky Sports.
"In the first half, maybe the best chance was for us.
"Our reaction was good because we kept doing our work.
"The impact of the substitutes was good. Some players like Willock also took a good step today. I can be positive about that. We finished 3-1 but also kept pushing and that is the spirit that I want."
