What a season Dele Alli is having at Tottenham.Having famously burst onto the scene at White Hart Lane last term with 10 Premier League goals, the 20-year-old has already surpassed that tally - and then some.Heading into Saturday's clash with Watford, Alli had notched 15 goals in England's top flight, level with Sergio Aguero and two more than Eden Hazard.His exploits over the past year have seen Real Madrid and Manchester City come calling, with both interested in summer moves, according to the Daily Mail.Tottenham, however, are confident of keeping the England star, especially so after he signed a new six-year deal with the club last September.And he kept up his impressive goalscoring form against Watford with yet another screamer from outside the 18-yard box.After playing a one-two with Son Heung-min down the left, Alli cut inside and unleashed a fierce strike to beat Heurelho Gomes and find the top-right corner.Check out Alli's latest wonder strike below.

Incredible. There were fears Tottenham would struggle when Harry Kane suffered ankle ligament damage against Millwall last month, but that's been far from the case.

Mauricio Pochettino's men have since claimed all three points against Southampton (2-1), Burnley (0-2) and Swansea City (1-3) and they entered the half-time break 3-0 up against Watford.

In Kane's absence, the trio of Alli, Son and Christian Eriksen have been fantastic and kept Tottenham's faint title hopes alive.

Victory over Watford will move them to within four points of Premier League leaders Chelsea, who travel to Bournemouth in Saturday's late game.
