Tottenham are closing in on the signings of £23.5million strike duo Vincent Janssen and Antonio Sanbria, according to a report.

The London giants have already reached an agreement with Southampton for midfield enforcer Victor Wanyama, who will join the club in a £13.5million deal after completing a medical earlier this week.

The Mirror claim Spurs are in talks with Roma to sign Sanabria for £11.5million and are already hopeful of landing Janssen for £12million from Dutch side AZ Alkmaar.

It is said that Mauricio Pochettino wants both deals wrapped up before the north Londoners begin their pre-season programme.

They would take Spurs’ summer spend up to £37million as Pochettino presses ahead to strengthen the squad ahead of their return to the Champions League next season.

Spurs had prioritised the signing of prolific Marseille striker Michy Batshuayi but a deal is on the backburner as they are unwilling to pay the combination of the £31million valuation and the player’s £100,000-a-week wage demands.

The London giants have started to explore alternative and cheaper options, including Alkmaar spearhead Janssen as they aim to strengthen their attack this summer.

As reported by Football Insider on Wednesday, Sanabria has rejected a move to Arsenal in favour of a switch to Tottenham.

The Sky Sports website, citing Italian publication Gazzetta dello Sport, claim the 20-year-old has turned down a deal with Arsene Wenger’s team to move to White Hart Lane.

In other Tottenham transfer news, Thierry Henry is convinced the club will lure big-name signings in the forthcoming windows.
