For me the benchmarks are.
European progress, cup finals, cup finals won, league position and points. This is his first season and we over shot expectation in Europe, we are not in any cup finals yet and the league is very up and down, so we need to wait and see. The comparisons to Souness is a stretch as it is very different circumstances now. Souness could sign up top players in their prime, Gerrard has not got the same financial clout. If anything Gerrard may have a more difficult job than Souness had and it will take more time to see the improvements coming through.
