The Gunners are looking to strengthen a squad which too often struggles to last the distance until May
Barcelona live updates
If El Clasico was won on Facebook likes, Barcelona (77m) would edge it over Real Madrid (75.5m). But when you look at a world map to see which club is the most popular in each nation, it's clear that Real has some serious catching up to do.
Barcelona manager Luis Enrique has confirmed that Luis Suarez will make his Barca debut during El Clasico at the Bernabeu on Saturday.
Suarez's return from his four-month ban for biting Giorgio Chiellini at last summer's World Cup adds spice to the classic encounter.
The manager now has a decision to make as to whether he starts his marquee signing on the bench or goes with a three-pronged attack with Suarez, Neymar and Lionel Messi.
Enrique is highly unlikely to split the Argentinian and the Brazilian, who have scored 13 goals between them in the last five games but he has revealed that Suarez will definitely feature in some capacity on Saturday.
"Today I cannot play this game but you will have assurance he will play minutes," he told Spanish media at his pre-match press conference. "How many? I do not know.
"It's an important occasion for him and he will have minutes."
Real Madrid assistant and former star player Zinedine Zidane has revealed there was never interest from the European Champions in Luis Suarez.
The former Liverpool striker is poised to make his competitive debut for Barcelona against Madrid this weekend, following his high-profile summer transfer.
Suarez has been unable to feature for Barcelona until now after biting Italy's Giorgio Chiellini at the World Cup, and being handed a four month ban from FIFA.
Speaking ahead of the season's first Clasico, Zidane said:
– Real Madrid assistant Zinedine Zidane
When Real Madrid want a player we work very hard to get the transfer done, but it was not a player we wanted.
He (Suarez) is obviously a very good player, but it was not a player we feel we needed to add to the squad. The players we acquired in the summer were exactly the players we wanted.
Lionel Messi showed manager Luis Enrique who's the boss at Barcelona after refusing to be substituted during a league match.
Enrique signalled for Messi to come off after 76 minutes of Saturday's 3-0 win over Eibar, but was forced to replace Neymar instead when Messi made it clear he wouldn't leave the field.
Former Barca star Frank de Boer later said:
"Leo also has great experience so he knows how he is physically. but when the coach says one thing, you have to listen."
Lionel Messi racked up his 250th Primera Division goal as he celebrated the 10-year anniversary of his Barcelona debut with a 3-0 win over Eibar.
Messi rounded off the scoring at the Nou Camp to keep the Catalans top of the table ahead of next week's El Clasico.
The Argentinian set up the opener for Xavi just before the hour-mark before Neymar volleyed in a second.
Messi's strike took him to within one of former Athletic Bilbao striker Telmo Zarra's record of 251 Primera Division goals and opened up the opportunity for him to become the league's all-time leading marksman next weekend at the home of arch-rivals Real Madrid.
