The latest Manchester United transfer news, views and rumours.
Louis van Gaal
The Dutchman has already spent heavily since moving to Old Trafford but the Guardian's report suggests he is happy with the progress his current squad are making.
That's despite United's worst start to a league season since 1986.
The Frenchman can play both as a centre-back and full-back and was frequently linked with a move to Manchester in the past.
Nothing materialised, though, and Koulibaly ended up joining Napoli for £8 million this summer. Van Gaal has reportedly turned his attentions to the 23-year-old, however, according to the Star.
The Scot has been out of management since being sacked by the Old Trafford outfit last season and, should he take the job, it would be Moyes' first venture into Europe.
