Manchester United are considering a return for former assistant manager Carlos Queiroz.
The 57-year-old was sacked as Portugal coach in September following a poor World Cup and a bad start to the Euro 2012 qualification campaign.
Portugal's anti-doping authority had also banned Queiroz from working in Portugal for six months, following an incident with their drug testers prior to the World Cup.
However, Queiroz is well thought of at United and is popular with a lot of the players and backroom staff.
While Sir Alex Ferguson is happy with Mike Phelan and Rene Meulensteen, there is a belief that room could still be found for Queiroz to add his experience, linguistic skills and meticulous planning.
Queiroz arrived at Manchester United in 2002 and stayed for a season before taking over at Real Madrid. He returned to Old Trafford for a further four years and in that time helped bring a more international flavor to United's transfer policy.
