Inter Milan stumbled in their bid to retain the Serie A title after throwing away a two-goal lead to draw 2-2 at Parma on Saturday, giving Napoli a chance to cut the champions' league lead to a single point. Goals in the first half from Matteo Darmian and Marcus Thuram appeared to have sent Inter on their way to moving six points clear at the top of the division ahead of their Champions League quarter-final with Bayern Munich. But Adrian Bernabe halved the deficit for Parma on the hour mark with a daisy cutter from distance, and the hosts were level nine minutes later when Jacob Ondrejka's strike was deflected past Inter goalkeeper Yann Sommer.
