Merino scored nine goals in all competitions for Arsenal last season.
The sight of Mikel Merino wheeling away in celebration after scoring while playing as a striker is something Arsenal fans have got used to over the past nine months.
And the midfielder-turned-frontman was at it again on Tuesday, scoring twice in their 3-0 Champions League win at Slavia Prague.
The 29-year-old was filling in for Viktor Gyokeres, whose muscle injury is "concerning" manager Mikel Arteta as the Swede prepares for further tests.
Thankfully, he need not be concerned about Merino's ability to step up and deliver for the Gunners, whose fourth straight success in the league phase extended their winning run to 10 in all competitions.
