Despite Arsenal’s perceived lack of transfer funds, we appear to have worked wonders and brought real quality into our club in this transfer window - with the loan signing of Denis Suarez from Barcelona.The midfielder will join for the rest of the season, with an option to buy the player when the loan deal ends. to protect their interests, Barcelona insisted on Suarez extending his current deal, guaranteeing a transfer fee should the move become permanent.So, what are we getting with the arrival of Suarez? Well, Unai Emery is a big fan of the player for good reason; the two are reunited after a spell at Sevilla under the current Arsenal boss. He made 31 appearances for Sevilla while on loan from Barca, so was used heavily for a then young player.Suarez is primarily used as a central midfielder, but has been utilised as a wide man for the Catalan club, and his technical ability lends itself to versatility. The player is thought to be a move to fill the impending Aaron Ramsey void, which lends itself to Suarez being used in the attacking quartet where Ramsey is often used.Suarez has experience in England too, being bought by Manchester City from his boyhood club Celta Vigo, and although his appearances were low, it means that the language barrier won’t be so steep, and the acclimatisation period should be shorter.With Xhaka, Guendouzi, Torreira and Elneny in the centre, and Emery’s comments on Suarez in his last press conference - where he intimated that Suarez would be used out wide - it means that we could have an addition to the width we lack, with Iwobi really the only name who is naturally a wide man, wit Mkhitaryan injured.Suarez is not known for his goals, and he may lack the frame for a physical battle, but to earn starts at the Nou Camp is no mean feat, and we look to have a player that can immediately add to our technical brand of football.Whether Denis is the sole signing for us this window is anyone’s guess, but he is an addition that we didn’t think we would get. A good signing and one that can help us maintain our push on two fronts.
