Gonzalo Higuain
The Argentine striker looked destined to join the North London outfit in the summer of 2013 [via Guardian Sport] until Wenger switched his attentions in trying to prize Luis Suarez away from Liverpool, but failed with a cheeky £40million plus £1 offer [via Mirror Sport].
Serie A outfit Napoli took advantage of the situation and landed Higuain, who has gone on to score 35 league goals in just two seasons.
He has been linked with a move to London on numerous occasions this summer [via Standard Sport] but is Wenger ready to resurrect a deal for the 27-year-old and reunite him with his former Los Blancos teammate Ozil?
His miss in normal time and poor penalty in the shootout of the Copa America final proves he struggles on the big occasions, but his goal-scoring record would be a welcome addition for a club gunning for the league title this season.
