The north Londoners' attempts to sign the 19-year-old on a six-month loan has so far been blocked by the Ligue 1 club despite the player keen to join Mauricio Pochettino's side

By Greg Stobart Tottenham 's negotiations to sign Paris Saint-Germain midfielder Adrien Rabiot on loan have reached an impasse with the Ligue 1 champions,understands.Spurs have agreed a six-month loan deal with the defensive midfielder's camp but have so far failed to reach an agreement with PSG over the terms of the move.The French club are refusing to sanction the deal even though Rabiot is eager to move to north London and has found his playing opportunities restricted in the French capital this month.PSG appear prepared to be willing to let Rabiot leave only if they first sign a replacement, with Newcastle midfielder Moussa Sissoko heavily linked with a switch to the Parc des Princes.Tottenham had hoped to negotiate an option to buy Rabiot at the end of the season but PSG are adamant the 19-year-old remains a key part of their long-term plans.The France Under-21 international only signed a new contract until 2019 in October but is desperate for playing opportunities having made just seven appearances in all competitions this season.Arsenal have also been linked with Rabiot but the player favours a temporary move to Tottenham where he can expect regular playing opportunities in Mauricio Pochettino's squad.Rabiot is understood to have a poor relationship with Laurent Blanc, but the PSG manager insisted earlier this week that he wants to keep the academy product at the club."I've always said he's a boy I want to keep," Blanc said. "My position is clear. He re-signed. He is part of the future of PSG. He is doing well after the first half of the season but it's very complicated on a personal level for him."I would like to keep him but this is a very complicated issue. I'll see if Adrian will be with us or not at the end of January. I want to keep him in the squad. I cannot be clearer."Tottenham are unlikely to be busy in the January transfer window despite their ambition to finish in the top four and qualify for next season's Champions League.Striker target Wilfried Bony is set for a £30 million switch to Manchester City and Spurs are happy to wait until the summer before making significant additions to the squad.The Londoners have considered moves for Aston Villa midfielder Fabian Delph and Burnley forward Danny Ings - who both have just six months left on their contracts - but believe the players will stay at their clubs until the end of the season.
