Arsenal are Serious about Signing this Quality Playmaker

Arsenal manager Arsene Wenger is not renowned for spending much in the winter transfer window on new players. However, the club are currently level on points with leaders Man City and must bring in more quality stars to push for the Premier League title.
If reports are anything to go by then the Gunners are linked with a January move for young Brazilian star Malcolm Silva.
Metro cite reports in the media claiming that Arsenal are serious about securing the services of the 18-year-old Silva.

As per the provided Metro link, Turkish side Fenerbahce have started talks with Corinthians to sign the starlet and hence Arsenal must act swiftly if they want him at the Emirates.
Last season, Malcom scored 4 goals and provided 3 assists in 25 league games for the Brazilian side. In your opinion, should Arsenal splash the cash to lure him keeping in mind that they already have more than a few top quality attackers?
