Hamburg coach Martin Jol believes qualification for the last four of the UEFA Cup is still far from assured despite Thursday's 3-1 quarter-final first leg victory over Manchester City.
City snatched a first-minute lead through Stephen Ireland at the Nordbank Arena, but goals from Joris Mathijsen, Piotr Trochowski and substitute Jose Guerrero put the Bundesliga side in the driving seat in the last-eight tie.
"We would like to forget the first minute for after that we played well," said Jol.
"It was a big wake-up call but we played well. In the first half we had five or six great chances, so we should have been up 3-1 already by then. I'd have liked to have scored a fourth."
Referring to next week's second leg in Manchester, Jol added: "They have terrific players like Robinho and Shaun Wright-Phillips and they play with three up, so they can cause us problems like they did in the first minute."
