Arsenal have reportedly added Zeno Debast to their shortlist of transfer targets. The Sporting defender is rumoured to be attracting attention ahead of the next transfer window, with insiders claiming preliminary talks could soon take place. Arsenal remain optimistic, but the deal is not without hurdles. Man Utd continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Arsenal's back line has been a real strength this season, conceding just 0.5 goals per game (3 in 6). Zeno Debast would be expected to slot into that unit and hold his own in an already solid setup. Sporting continue to be linked with Ioannis Konstantelias, Fotis Ioannidis and Jota while Arsenal are also rumoured to be tracking Denzel Dumfries, Piero Hincapie and Karl Jacob Hein.
