We are approaching that time of year again when, with no actual football being played, the transfer window takes centre stage.

Some very large fees will undoubtedly be thrown about with plenty of that sure to be going to Championship clubs in exchange for some very exciting players.

One player who is set to be at the centre of plenty speculation is Leeds United's exciting academy product Jack Clarke.

Clarke burst onto the scene last season for the Whites, with the 18-year-old quickly becoming a favourite of the fans after a host of fearless, attacking displays on the wing, but he is attracting interest from one of the Premier League big boys.

Tottenham Hotspur are apparently the club leading the charge to snap up the exciting talent but it Leeds are not about to let him go cheaply.

A report from the Daily Mail suggests that the North London side will have to cough-up £20million to bring Clarke to the club.

It is easy to see why they want him. After snapping up Dele Alli for a bargain back in 2015, Spurs have reaped the rewards for dipping into the Football League before.

However, whilst Clarke is clearly a bright prospect for the future, with what is likely to be a limited transfer kitty again, Tottenham must be wary of overpaying.

As much as he has shown flashes of brilliance, that is largely what they have been - flashes.

Coming into the side towards the end of 2018, Clarke enjoyed a fruitful spell of starts and cameos, racking up two goals and two assists within just over a month.

However, that was very much it for the season for the attacker. After being taken to hospital with an illness during their clash away to Middlesbrough, he missed six straight matches on the sidelines as the club took extra care of his condition.

In eight cameo appearances since then, he has rarely threatened to produce. It is worth mentioning that his return coincided with the club's chase for second place fizzling out, so it is not like he was returning to the perfect environment.

But it is well worth Spurs taking note of. Yes, Clarke is a top talent and is worth a lot to Leeds. But the somewhat unpredictable nature of his performances should be a warning to them not to overspend.
