Tottenham are targeting four main first-team signings this summer, Football Insider sources understand.

Manager Mauricio Pochettino will not have a huge budget to work with despite the club’s return to the Champions League for the first time in six years.

But there will be the opportunity for the Argentine, who has turned a transfer market profit in his first two years at the helm, to strengthen a squad that fell at the final hurdle in the recently completed campaign.

A well-placed Spurs source has told Football Insider that Pochettino and his recruitment staff are in the market for a new striker, central midfielder, wide attacker and centre-back.

As revealed by Football Insider, prolific Marseille spearhead Michy Batshuayi has been heavily scouted by the north Londoners and is their No1 choice to provide high quality back-up to Harry Kane next season.

Spurs are also keeping close tabs on the likes of Basel ace Breel Embolo, Bournemouth’s Callum Wilson and long-term target Saido Berahino of West Brom.

In central midfield, Spurs remain keen on signing Victor Wanyama, who is expected to leave Southampton this summer after rejecting a new contract offer.

Pochettino is also looking to add a pacy player out wide and a fourth senior centre-back to complement Toby Alderweireld, Jan Vertonghen and Kevin Wimmer.

Spurs are likely to have to sell to land some of their main targets, which could mean them listening to offers for fringe players like Nabil Bentaleb, Ryan Mason and Tom Carroll. It has also been reported that Heung-Min Son could leave the club just 12 months after joining from Bayer Leverkusen for £22million.
