Spaniard Fran Merida has signed professional forms with Arsenal. Merida initially joined the Gunners last season after playing for Barcelona's youth side.
The 17-year-old midfielder has made seven reserve team appearances this season as well as featuring for Arsenal's Under-18 side.
Merida was an unused substitute for the first team when Arsenal played at Premiership rivals Everton in the Carling Cup earlier in November.
