If their recent slump proves anything, it’s that Tottenham Hotspur need to bolster their squad and especially add more firepower to back up their stars.

While Harry Kane’s amazing run means he’s an indispensable figure, Spurs need a proper cover for him now that Fernando Llorente has revealed to Marca that he'd be keen on returning to Spain to see out his career after being touted (via Cadena Ser) with a return to Atheltic Bilbao during the January window.

The Spaniard’s been a go-to substitute option for Mauricio Pochettino, who's relied upon his towering stature and clinical ability up front to bail him out of tough situations, to varying effect. Clearly, the World Cup winner has proven a good player at times, though can look well past it and his worst.

Llorente’s potential and seemingly inevitable departure depletes Spurs' already limited squad, but rather than splashing out big bucks to sign a proper replacement to him, Pochettino should rely on youth, something he's proven very good at in the past.

Tottenham’s youth structure is blooming, keeping up their reputation of producing quality players. They have some promising players coming up, including Kazaiah Sterling and Shayon Harrison, both currently on loan to Sunderland and Melbourne City FC respectively.

Sterling’s been the more impressive outlet for Spurs u-23 side, impressing in Premier League 2, where he’s scored four goals and assisted twice in seven appearances (stats via Transfermarkt). Harrison’s also scored four goals (stats via Transfermarkt), whilst also making three appearances for Melbourne in the A-league. Both have been sent to gain experience, indicating that Pochettino has plans for them.

With Son Heung-Min now also able to shift into the middle, there’s no need for another striker as Spurs should look to fill their defensive holes instead.

Indeed, Sterling and Harrison can both add unpredictability to Spurs game, becoming valuable backup options because of their clinical goal-scoring ability and exuberance. Daniel Levy doesn't seem to be in much of a rush to spend money these days, so promoting from within could certainly please him.
