Shaw, 18, has been one of the stars of the Premier League season, shining at left back for Mauricio Pochettino's Southampton side, earning his first England cap in the process - and is now in a great position to earn a seat on the plane to Brazil for this summer's World Cup as a result.
But as with any player in the Premier League, impressive displays attract interest from the 'bigger' sides in the division, and that has been the case with Shaw. Chelsea, Manchester City and Manchester United have all been strongly linked with big summer bids for the starlet, but it seems it's United who have won the race for his services.
Reports today suggested that United were confident of securing a £30m deal for Shaw before the World Cup, meaning he would almost certainly become the new starting left back at Old Trafford, replacing Patrice Evra in the process.
Alex Sandro, Porto - Sandro, 23, left Santos in Brazil for Porto in 2011, and has been impressing in Portugal ever since. With a burgeoning reputation in European football and six caps for Brazil, Sandro is a rising star at left back, and Mourinho could seek to swoop on his former club to land his left back of the future.
Alberto Moreno, Sevilla - Just 21, Moreno has already established himself as one of Sevilla's star players since bursting on to the scene in 2012. Moreno, who could go to the World Cup with Spain this summer, already has one cap for his country and would be a superb signing from Mourinho should he chase his signature.
Ricardo Rodriguez, Wolfsburg - Linked with the Blues last summer, 21-year-old Rodriguez has been impressing in the Bundesliga for Wolfsburg since his 2012 switch from FC Zurich. A number of other teams have been linked with the Swiss international, meaning Mourinho may need to move quickly - particularly with a World Cup showing on the horizon.
Filipe Luis, Atletico Madrid - A key player in Diego Simeone's Atletico side, Luis is arguably the most underrated left back in world football right now. Relations between Atleti and Chelsea are seemingly strong given the Thibaut Courtois situation, and with Mourinho chasing Diego Costa, maybe he should enquire about Luis as well.
Fabio Coentrao, Real Madrid - A player Mourinho worked with at Real Madrid, Coentrao has been on the fringes at Real, sitting behind Marcelo for the majority of his time at the Santiago Bernabeu. Believed to be on the move this summer, the Portugal international would be a solid if unspectacular option for the Blues.
