The 3-2 win in the FA Premier Academy League followed victories over MK Dons in the league last weekend and Southampton in the FA Youth Cup on Wednesday.
Alex Inglethorpe opted to go with a completely different starting XI from St Mary's and was rewarded with a fine first 80 minutes when the lads established a 3-0 lead through Ryan Mason, Sol Asajile and Jon Obika (pictured right).
As coach Alex reported, they then 'made it exciting' by conceding two late goals, but the win was never really in doubt.
"We didn't have one player in the starting line-up from midweek and that's a credit to the medical staff here and the players themselves," said Alex.
"We dominated from the start and might have already been 1-0 up when Jon Obika touched in a shot from Kyle Fraser-Allen that might well have gone in anyway, but he was in an offside position.
"We went 1-0 up after 20 minutes when Jon Obika was fouled and Ryan Mason tucked away the penalty.
"We made it 2-0 about 15 minutes later when Matty Wells swung in a free-kick and Sol Asajile did well to get between defenders and poke home from about eight yards.
"Jon Obika had a couple of chances so it was good to see him make it 3-0 after 65 minutes when he forced his way into the box, beat a couple of players and smash it home.
"We'd made our three substitutions when Ryan Mason picked up an injury and had to come off, so we ended the game with 10 men.
"I was still disappointed with the defending in the last 10 minutes because until then, Coventry had hardly created a chance. They made it 3-1 after 82 minutes when the striker got between defenders to meet a cross and then scored again with five minutes left, so it went from a game where we'd led 3-0 and might have made it more comfortable to a nervous last three or four minutes, but we deserved to win. We're on a decent run and we've won a lot of those games."
In fact, the win made it seven games unbeaten, one defeat in 10 and eight wins in the last 10 matches.
Spurs U18s: Button, Smith, Mtandari, Wells (Hutton, 70), Shehu, Caulker, Fraser-Allen, Asajile (Kasim, 60), Obika, Mason, Townsend (Olsen, 80). Unused subs: Dalton, Cox.
Our Under-18s completed a perfect week with their third win in seven days by overcoming Coventry City on Saturday.
