Unai Emery has challenged Denis Suarez to finally make an impact as Arsenal bid to climb back into the Premier League's top four against Newcastle on Monday.
Suarez has struggled since his January loan move from Barcelona and the Spanish midfielder is yet to make a competitive start for the Gunners.
But a series of impressive displays at Arsenal's recent training camp in Dubai could have earned the 25-year-old a chance to shine when Newcastle visit the Emirates Stadium.
Suarez played the full 90 minutes and created a goal for Carl Jenkinson in Arsenal 3-2 friendly victory over Al Nasr.
With Granit Xhaka facing a late fitness test and Lucas Torreira suspended, Arsenal boss Emery is encouraged by Suarez's timely improvement.
"He is okay for starting in the first XI, to give us this impact," Emery said. "We are going to need everybody, every player for the next matches.
"We decided to go away to train for four days and play a match in Dubai. But it's the same idea, the same spirit."
Asked about the time it had taken Suarez to settle in north London, Emery added: "It's normal. Now we have a lot of players ready, with a big mentality and with a big performance to play and help us."
"Xhaka also rested and we are going to wait for Saturday and Sunday. But the first previews from the doctor's analysis is that they can be okay to play on Monday."
