Tottenham are considering a shock move to re-sign Gylfi Sigurdsson from Swansea. Sportsmail understands that Spurs boss Mauricio Pochettino believes that the former Tottenham playmaker could be a better and cheaper alternative to signing long-term target Ross Barkley from Everton. Pochettino has been keen on Barkley for months and still rates him highly. But the Tottenham manager knows that Everton want up to £50million for the 23-year-old and is now considering a £25m move for a player he always believed should never have been sold in the first place. Sigurdsson moved from White Hart Lane to Swansea in the summer of 2014. Pochettino had just arrived and was not involved in the decision.
