Emery urges Suarez to take his chance as Arsenal chase top four
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."
Emery was keen to work with Suarez again after signing on loan at Sevilla in 2014-15.
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."
Beating Newcastle would give Arsenal a 10th successive home league win, equalling a run they last enjoyed in the 1997-98 season in Arsene Wenger's first full campaign as manager.
A victory is essential after Arsenal dropped to fifth place on Saturday as a result of Manchester United's 2-1 win over Watford.
