They are reserves at these famous football clubs but, as it turned out in the opening match of the 2018 International Champions Cup yesterday evening, the second stringers ended up playing first fiddle for both Arsenal and Atletico Madrid.
Speaking last month, Emery said: "I know him but we haven't made a move for him".
Speculation is mounting that Arsenal chief executive Ivan Gazidis is set to follow manager Arsene Wenger out of the club, marking the end of an era, to join AC Milan.
"He has a lot of experience, which will be good for the group and the team, and his incorporation has always been positive".
The match went to penalties and Atletico capitalised to take the win after a relatively poor performance from the Arsenal players at 12 yards.
The Wales global, who joined the club in 2008, is in the final year of his contract.
"He is 17 years old but he has grown up in the academy and we need to give the young players the opportunity to work with us every day and play matches like today". The club's previous captain, Per Mertesacker, retired in the summer so the position is vacant, and Emery believes Ramsey has the credentials to be a contender for one of the five roles on offer.
The Spaniard said: 'Aaron is an important player for us, and the contract is one thing for the club and the player.
Unai Emery made just one change at the start of second half as Petr Cech replaced Arsenal's new goalkeeper Bernd Leno and the gunners didn't take long to get an equalizer as they scored after Emile Smith Rowe scored through a stunning shot to make it 1-1.
The 53 year-old has struggled to become a favourite with the fans at the Emirates after failing to meet promises.
Gazidis is also in Singapore with the team this week, and Emery said the two talk "every day". I want him to stay with us, to work with us, to give the team big performances with his quality.
