(Reuters) - Central Coast Mariners coach Mark Jackson is confident his team can continue to challenge on multiple fronts after Mikael Doka's injury time winner against Wellington Phoenix took the Gosford-based side top of the A-League standings.

Doka struck in the 91st minute of Saturday's clash at Central Coast Stadium to move the Mariners ahead of Wellington due to their greater number of wins this season and keep the club on track for a hat-trick of titles.
