Paok, all sorts of q's arise re the Arsenal squad. The meaning, construction, and punctuation of either sentence is governed by a number of unknown factors. For instance, is the squad officially named, where, 'squad' should be in caps? in which case 1st s/b "Arsenal Squad's"
Many others arise. Frinstance is there only one Arsenal? If more, then isn't the 2d somewhat ambiguous suggesting several additional uncertainties, frinstance whether we're considering an arsenal squad or a rotation system
