Manchester United chief executive David Gill has hinted that there could still be some transfer activity at Old Trafford before the new season begins.
Earlier in the week, United boss Sir Alex Ferguson called a halt to his summer spending after revealing his frustration at the 'unrealistic' and in some cases 'stupid' fees being paid by some clubs.
Ferguson has lost Cristiano Ronaldo and Carlos Tevez during the summer and has spent only a fraction of the transfer fees he has recouped.
Luis Antonio Valencia, Michael Owen and Gabriel Obertan have arrived at Old Trafford and Gill has hinted that perhaps the club's summer transfer activity is not yet fimished.
United have also been linked with moves for Internazionale striker Zlatan Ibrahimovic and Atletico Madrid's Argentina forward Sergio Aguero.
Speaking about his tasks on the club's forthcoming pre-season tour to Asia, Gill revealed: "I will start each day with the usual emails and correspondence and I'm sure there will be some player activity going on while we are over there."
