Spurs are hoping to secure a loan deal for the England international before the close of the transfer window, with the 23-year-old having fallen down the Old Trafford depth chart.
The clubs are in advanced negotiations over a loan fee of around 2 million pounds and Spurs have agreed to pay the 23-year-old’s full salary, with the deal likely to be completed on deadline day Monday.
Welbeck came close to leaving United at the end of last season, but opted to try to force his way back into the first team when Louis van Gaal took over following the World Cup.
However, the player and manager have been speaking over the last few weeks regarding Welbeck's future at the club – and following the arrival of Angel di Maria, the England international has found himself even further from first-team action.

With United willing to let him go, the likes of Newcastle, Sunderland and Hull all inquired about Welbeck, with Arsenal also monitoring the situation. But Tottenham was always Welbeck’s preferred option, and an agreement is now close between the two clubs and the player.
Spurs manager Mauricio Pochettino values the England international’s pace and versatility as a player who can play either centrally or from a wide position.
Welbeck’s arrival could spell the end of Roberto Soldado’s stay at White Hart Lane, with the Spaniard drawing interest from Italy and Spain.
Atletico Madrid has retained its interest from earlier in the summer but is so far only proposing a loan deal, with Tottenham preferring a permanent transfer.
The 29-year-old has failed to live up to expectations following his arrival from Valencia for 26 million pounds last summer, scoring just six goals in 29 Tottenham appearances.
He has found himself out of the side again at the start of the new season, with Emmanuel Adebayor preferred to lead the attack in Tottenham’s opening three league fixtures.
