Arsenal are working to make new additions to their squad before the winter transfer window slams shut on Monday, according to The Daily Express.The Gunners were bracing for a busy transfer window ahead of January. However, with just four more days remaining this month, Mikel Arteta's side are yet to make a signing, while Ainsley Maitland-Niles, Sead Kolasinac and Pablo Mari are the only outgoings.Arsenal identified centre-forward as a position that needed strengthening ahead of the winter transfer window. They worked hard on a deal for Fiorentina hitman Dusan Vlahovic, but appear to have lost to Juventus in the race for his signature.Despite the setback in their pursuit for Vlahovic, the north London giants are looking to bolster their roster. The Gunners could bring in a new goalkeeper and a midfielder before the end of the month.According to the aforementioned source, Arsenal are confident about acquiring the services of USA international Matt Turner from MLS outfit New England Revolution. Arteta's side have not made much progress in their attempts to sign the goalkeeper since making an opening offer last week, but they remain hopeful of landing him.Taylor Twellman@TaylorTwellman Breaking news!!@Arsenal have put in a strong bid for @headdturnerr from the @NERevolution today.
