The South Korean ended a seven-game scoring drought as he nodded home 11 minutes from time just when Spurs were on the rack.

They had taken a first-half lead through Dele Alli, but Teemu Pukki's penalty drew Norwich level and it was the visitors who were in the ascendancy.

Spurs rallied to get the win, their first in the Premier League since Boxing Day which cuts the gap on Chelsea to six points, but not many people, not least Jose Mourinho, will think they are capable of finishing in the top four on this showing.

They did at least find the net, their first in the league since Harry Kane's possible season-ending injury and Mourinho will hope by the time they play Manchester City in 10 days they will have a replacement in.

Real Sociedad striker Willian Jose is the latest target to be linked and the Brazilian was left out of the La Liga side's Copa Del Rey win over Espanyol at his own request.

For Norwich, defeat will be hard to take as they missed the chance to cut the gap to safety, which still stands at six points.

Leicester returned to winning ways with a 4-1 thrashing of relegation-threatened West Ham to maintain their push for Champions League football next season, but it came at a cost.

Following shock back-to-back defeats to Southampton and Burnley, the Foxes were again at their superb best as goals from Harvey Barnes, Ricardo and a brace from Ayoze Perez ensured they maintained their stranglehold on third place.

But after what has been a relatively injury-free season for City, boss Brendan Rodgers saw midfielder Nampalys Mendy and star striker Jamie Vardy limp off in the first half.

Rodgers at least witnessed a performance that was on a par with those that saw Leicester win nine matches in a row - eight in the league - from mid-October through to early December that had propelled his side up to second and into title contention.

The Hammers had no answer for City's powerful cut-and-thrust, and but for often lamentable final passes inside the area then the scoreline could have been far more emphatic.
