Pompey ensured they would end the year at the top of the League One table with a 5-2 victory at Fleetwood.

But Dean Marney saw red after the break, with Brett Pitman then converting a penalty to level the scores.
Anton Walkes found the top corner to send the Blues back into the lead and Jamal Lowe added a late brace to give the scoreline a gloss.
