Well, one Arsenal fan responded to the news of Suarez's arrival by taking to YouTube and posting a video titled: "11 Times Denis Suárez Showed His Class!"
He could slot straight into the middle of Arsenal's midfield, or alternatively be played out right on the wing, where he used to feature for Emery in Spain. If he starts, I have confidence in him'.
In an official video released by the club, Suarez scored a lovely goal at the end of a training session, bending an unstoppable shot in off the post from the edge of the box (at minute 4.46) - much to the delight of Alexandre Lacazette.
"It will be a tough match - we are playing against the best", he said. And while this is obviously because the pair play in similar midfield roles, plenty of Arsenal fans have noticed that the new arrival also bears a striking resemblance to the outgoing Welsh worldwide. The coach, who has coached the player before, said, "Firstly he knows the language - he can speak English, which is important for us". It is a good challenge for him and for us.
Suarez looks as if he could come in and make an instant impact for Emery's men.
When asked what Suarez's best position is, Emery replied: "He can play on the right or left, or inside like a number 10".
"After, he played with Barcelona, not in the first XI a lot of times, but he helped them there and played in the Champions League, in an important team with important players".
In the announcement Barca stated Suarez would spend the rest of the season on loan in the Premier League, while also revealing he had penned a contract extension until 2021.
'They lost at Newcastle so they need to win, ' said Emery. They are playing at home and for us it will be very hard. But we want to show everybody we can play.
He has character, big character, and he has the quality to play here.
