Arsenal have won their last three Premier League games following victories over Sunderland, Aston Villa and City.
Unsurprisingly, Mertesacker was in good form on Christmas morning as Arsenal posted a message from the Big Friendly German on their Twitter page.
Merry Christmas everyone !!! Enjoy the time with your families and beloved ones … https://t.co/HImaRtS28F
