Emery also praised the attitude of Aaron Ramsey as the Wales worldwide continues to be linked with a move away from the Emirates Stadium.
Arsenal spent around £70m on four players last summer - Lucas Torreria, Matteo Guendouzi, Sokratis and Bernd Leno with Stephan Lichtsteiner also arriving on a free transfer - and signed striker Pierre-Emerick Aubameyang for a club record £56m in January 2018.
Arsenal have already been tipped to pursue the services of Denis Suarez from Barcelona but they are experiencing a similar predicament with the Spanish club wanting a straight-cash deal for the Spaniard. Every day he's here with us, he's working very well.
When asked whether he would give players a break or make changes to his training regime, Emery answered: 'We are doing that.More news: May stares into Brexit abyss as UK Parliament takes control

"I don't know his [Suarez's] situation".
"If we can find one player who can help us like we need, with the quality and a different player for getting in our squad, we are going to do it".
"I respect his decision a lot". His response has been very good in training and matches with good performances. I asked in the last match at Blackpool (in the FA Cup) if he is okay to help us play and he said, "Yeah, coach, I want to play" and he played with a very big commitment to us.
He said: "We can not sign permanently".
Defenders Hector Bellerin, Laurent Koscielny, Shkodran Mustafi, Nacho Monreal and Dinos Mavropanos have also returned to training this week and in contention to feature.
