Arsenal took full advantage to set up an intriguing title battle when the Premier League returns from a six-week hiatus on Boxing Day. Martin Odegaard led by example for the Gunners as the Norwegian fired home twice from close range in the second half. New Wolves boss Julen Lopetegui was in the crowd before officially taking charge on Monday and has work to do in the second half of the season with Wanderers now bottom of the table.
