The Egyptian midfielder became the club’s first signing of the January transfer window last week, as he completed a move from FC Basel.
He has spent the start of this week training with his new teammates after being named as an unused substitute for Sunday’s 0-0 draw at Stoke City.
“I’ve trained with him and he’s a good player, very talented but first of all he is a good guy - I think he will settle well into the team,” Giroud told arsenal.com.
“I think he’s basically a box-to-box midfielder, so he can attack and defend, run a lot and has good power and technique. He is quite a complete player.”
“It always takes time to adapt to English football because there is a lot of intensity, it is very physical and even tactically [you must get used to it] - but I think Premier League football will suit him well.”
Manager Arsene Wenger will now be eager to see if Elneny can come into the side and provide competition for defensive midfielder Francis Coquelin.
The Frenchman has become a key player in the side since his breakthrough last season, and has been sorely missed since picking up a long-term injury in November.
Mathieu Flamini has stepped up admirably in his absence, but cannot bring the energy that his compatriot brings to the role.
That is something that Elneny can offer, and Wenger will be hopeful he can ease the burden on Flamini in the second half of the campaign while Coquelin continues his comeback.
