The Gyokeres conundrum: Do Arsenal need a striker upgrade?

Last week was unquestionably the best of Viktor Gyokeres' Arsenal career so far. On Wednesday, the £64 million ($86m) summer signing confidently converted a penalty in the Gunners' 1-1 draw with Atletico Madrid in the first leg of their Champions League semi-final at the Metropolitano. Three days later, Gyokeres scored two goals and created another in a 3-0 win over Fulham that extended Arsenal's advantage at the top of the Premier League to six points.
