Arsenal sign Bruno Guimaraes, Arteta faces squad juggling act

Arsenal have confirmed the signing of Bruno Guimaraes, adding to an already stacked squad. The move strengthens the Gunners further but hands Mikel Arteta a tough job. With more top players competing for minutes, the manager has to keep everyone content. Squad harmony becomes the hard part. Guimaraes arrives as Arsenal push their title challenge, but the numbers in midfield are now crowded. Arteta will have to make calls on who starts and who sits. Getting that balance wrong could unsettle a group that just added a serious name.
