Arabic term (edited): ������ ��� ����� ����

This is how we'd say it idiomatically in the UK at least:

Protectors claimed the vital three points to move clear at the top of the table.

But champions Arsenal hit back through a Robert Pires penalty to go a point clear at the top of the table.

Or even "sitting pretty at the top of the table":

Having started the new season with back-to-back victories, Dagenham went into the game sitting pretty at the top of the table

The Arabic literally means "sitting on the summit alone"; it doesn't much in English, particularly not in sporting terms. The terms I have suggested are used particularly in match reports and other media.
