Gil has struggled to make an impact during his time in north London and it was thought he would be shipped out by the club in the summer transfer window.
The Spaniard had to undergo surgery after suffering an injury this summer though and he has yet to make a competitive appearance under Postecoglou.
Gil was on the bench against Luton Town and the attacker is ready to be called upon by Postecoglou whenever needed.
The Spurs boss is jubilant to get him back fit and stressed the importance of having an option on the left-wing as both Perisic and Solomon are injured.
“He can be really important for us”, Postecoglou said at a press conference when asked about Gil returning to fitness.
“He is one like I said the last couple of weeks it has been great to have him just working really hard at training.
“He has missed all of this season so far and it is well-chronicled that we lost Perisic and Solomon who play in that left-wing position.
“Having Gil fit and available again is great for us.“
Tottenham will return to the top of the Premier League table if they can beat Fulham in north London this evening.
