Norwich City's supersubs are proving to be worth their weight in goals – and none more so than Simeon Jackson.

The Canada international's late winner in the FA Cup at West Bromwich Albion was the eighth time a substitute has scored in the Canaries' last 16 matches in all competitions.

Jackson's 85th-minute goal in City's 2-1 fourth round win at The Hawthorns was his fourth in his last seven outings, three of them after coming off the bench.

He scored in the 2-2 draw at Wolves and headed a late equaliser in the 1-1 draw at home to Fulham.

In all, eight of 24-year-old Jackson's 17 goals for the Canaries have come as a substitute, including that whirlwind Championship hat-trick in the 6-0 demolition of Scunthorpe last April.

Astute use of substitutes has played a major part in Norwich's success under manager Paul Lambert over the past two and a half seasons – for the extra men have provided no fewer than 34 of the 225 goals City have scored in his 124 matches in charge in all competitions.

Even more importantly, not one of those 34 goals has been a wasted effort, contributing to 19 victories and eight draws.

This season, skipper Grant Holt has scored crucial equalisers in Premier League matches against Liverpool and Blackburn and the winner in the home game against Queens Park Rangers after coming on as a substitute.

Joint top scorer Steve Morison has scored twice from the bench, including the late winner in the return fixture against Rangers at Loftus Road.

Said Jackson: 'We have all done it as a squad throughout the season. Everyone. Holty has done it. Moro has done it. It just shows what we are about and what we are trying to achieve. It is always a good feeling to score, even coming off the bench. You don't really mind how you score, as long as you do.'

Wes Hoolahan struck four times in the Championship last season as a substitute, with a goal in the 4-1 home win over Ipswich and a hat-trick in the 4-2 home victory over Sheffield United.

Oli Johnson was the real supersub in League One, scoring four times, including a late double in the 2-1 home win over Southend.
