we have got decent players in who replaced players like Trott and Kp and Prior.......but...if your talking spin bowling Swann was by far the best English spinner in the 30 years ive been following England.
So real quality is few and far better anyway.You could go back to Edmonds, Embury, Tufnell,Panesar,Such(!)......
but actual match winners don't come along that often.
Spin wise now I couldn't tell you who is the best spinner in the Country right now to be honest... Rashid?
Ali is a part time bowler who hopefully will improve.But there's no way he should be seen as a front line spinner.
