Tottenham Hotspur's hopes of mounting a title challenge this season have already been dented by Manchester City's ominous start and a further delay to their stadium move, but a recent report from the Daily Express suggests their biggest blow could yet be on the horizon.

Indeed, the end of the transfer window has not fully guaranteed that Mauricio Pochettino will be able to keep all of his best players this season. Although summer business is over for the Premier League, plenty of clubs across Europe can still dip into the English top-flight in order to bolster their options, and that's exactly what Paris Saint-Germain are planning on doing according to the Daily Express.

According to the report, PSG are interested in signing Christian Eriksen before August 31st in a deal which could be worth a whopping £100 million.

The fee which has been quoted is certainly representative of Eriksen's true value, and that notion is a testament to how rapidly he has developed since arriving in north London from Ajax for just £12.15 million in 2013.

During his career with the club he has established himself as one of the first, if not the first name on the team sheet, as the creative quality he provides is unrivalled within the Tottenham squad.

With that to consider, it's absolutely imperative that Daniel Levy does not jump at the chance to make a fantastic return on his investment if the French giants eventually table an offer of £100 million.

Eriksen (valued at £72 million by Transfermarkt) is an irreplaceable cog in a machine which has taken years to slowly mould together under Pochettino's watchful eye, and taking him out at this stage in the club's development could have extremely negative consequences for their long-term development.

The likes of Dele Alli and Harry Kane who have thrived under Pochettino owe a great deal of credit to the incisive passing and creative flair which the Denmark international has consistently provided, so allowing him to leave would serve to single-handedly destroy their title ambitions and could even leave them struggling for a place in the top-four.
