Wigan manager Roberto Martinez was in no doubt he had made the correct decision in introducing Ben Watson after the midfielder converted an 87th-minute penalty with his first touch to rescue a valuable point against Stoke.

Jonathan Walters scored from the spot with 13 minutes remaining, after Wigan captain Gary Caldwell had been sent off for handball, to cancel out Victor Moses' opener on the stroke of half-time. Substitue Cameron Jerome then put Stoke back in front before Watson sent Thomas Sorensen the wrong way after Ryan Shotton had been penalised for a tug on Hugo Rodallega's shirt.

Asked whether he had taken a gamble by bringing on Watson to take such a crucial spot-kick, Martinez replied: "In football, it's not (a case of) being brave, it's trying to do the right things."
