The Gunners are in the thick of a four-way battle for two Champions League qualification spots in the Premier League and have one foot in the Europa League semi-finals after earning a 2-0 quarter-final first leg win over Napoli on Thursday.
Ramsey – who will leave the Emirates Stadium for Italian champions Juventus at the end of the season – scored the opener against Napoli and Emery wants him to continue his fine recent form in the closing weeks of the season.
“It’s not easy for him after he signed for Juventus but his focus is to help us and his attitude is a very amazing attitude towards each training session,” he told a media conference ahead of his side’s visit to Watford on Monday.
“I continued speaking with him about doing something very important in the last matches here in two competitions that are very important for us.
“He wants to do something important for the supporters and I want to do something important for him in his last matches here.”
“At Watford, we need to be defensively hard and strong, like we are at home now, and in the attacking moments use the best opportunities to find chances to score.”
