Al Mubhir is interesting, he's once raced (October) and once a winner. He has a good pedigree and the form of his win for the level looks very good.
Bare with me here, - Al Mubhir beat Filistine (John Gosden) by a comfortable length. Filistine then won a few weeks later in a novice where himself and Silent Speech, pulled 6l clear of the third.
Silent Speech is very useful and he's ran to a mark of 100 in four runs and is unlucky not to be 2/2 in Meydan this season.
The substance of Al Mubhir's form is all there, and he has a nice pedigree, he will likely need this run but he's interesting and could well be very useful.
