Japan striker Shinji Okazaki got off to a winning start on his Premier League debut with Leicester City on Saturday, but admitted his frustration at not being able to get his name on the scoresheet in a 4-2 defeat of Sunderland.

Okazaki produced an energetic performance but was guilty of missed opportunities either side of the break after starting alongside England forward James Vardy.

Vardy headed Leicester in front on 11 minutes and threatened again when he set up Okazaki, who couldn't get a clean connection.
