Alli began the night collecting his PFA Young Player of the Year award in front of the Tottenham supporters but the midfielder let his frustrations boil over early on with an unnecessary act of petulance.
discount ace 16.2 Referee Mike Jones did not seem to see the incident but the 20-year-old could yet face a three-match suspension if found guilty of violent conduct, a punishment which would rule him out for the rest of the season.
Tottenham dominated the opening exchanges and within 12 minutes had twice hit the woodwork as Harry Kane bounced a one-two off Alli, but saw his finish tipped onto the post, before Christian Eriksen's whipped free-kick grazed the top of the crossbar.

Surviving the early onslaught, West Brom dropped deep, happy to let the hosts dictate possession while Spurs fans vented their frustration as early as the 22nd minute when the Baggies took their time over a throw-in.
In fact, the visitors could have taken the lead when Craig Gardner blazed over from inside the area and moments later Spurs made them pay, as Jan Vertonghen and Dawson tussled to meet Eriksen's free-kick, with the latter bundling the ball under Boaz Myhill for an own-goal.
With the deadlock broken, Tottenham began to enjoy themselves, Mousa Dembele flicking his way nonchalantly through Darren Fletcher and the home supporters launching into an optimistic rendition of "Leicester City, we're coming for you".

Salomon Rondon heading Gardner's cross wide was a warning which went unheeded as in the 72nd minute Dawson climbed above both Dier and a flailing Hugo Lloris to head home an equaliser from a Gardner corner.
Dier took a blow to the head trying to defend the goal and had to be substituted, while Nacer Chadli was also introduced late on as the hosts desperately searched for a winner.
There were to be no late heroics, however, as Tottenham's title challenge finally hit the buffers, leaving Leicester on the brink of glory.
