Just the one change for Arsenal - but it's a big one. Mesut Ozil is in for Alex Oxlade-Chamberlain.

When Petr Cech swapped his place as part of the furniture at champions Chelsea for a spot in goal at Arsenal last summer, there must have been a large part of him wondering if he had made a mistake.

After a decade of glory, four titles, four FA Cups and a Champions League, Cech was stepping into the [relatively] unknown. Though he didn't have to move house, which is always a bonus.

What I'm almost certain that he did not envisage was that by the time he met up with his old pals at the end of January he would be 19 (NINETEEN) points above them.

An extraordinary season in a lot of ways. Will Cech keep on smiling tonight?
