Rumour has it that Portugal and Porto Midfielder Joao Moutinho is his top target now (according to articles on the Dailymail and the Sun).
Ferguson said: 'We're working on one or two things but there's nothing really to tell you to be honest.
'We always try to get our work done at the end of the season – we spent a good deal of time sorting the deal with Shinji and we'd agreed a deal with Nick Powell before the play-offs which was a good move by us because the boy had an outstanding final at Wembley.
'When you don't get deals done immediately and you're negotiating with a club over a long period, then you can't expect to just snap your fingers and get it done,' he said.
It seems that a move for Moutinho has come off the back of utd becoming fed up with Spurs demands over the fee for Luka Modric, which was originally ment to be in the region of £25m rising to £30m.
But Spurs have now quoted £40m for the Croatian and United will not pay that.
