UPDATE 2-Soccer-Hamburg recover from shock start to beat City

* Ireland puts City ahead after 35 seconds

* Mathijsen equalises within nine minutes

* Trochowski and Guerrero add to Hamburg tally (Adds quotes)

HAMBURG, Germany, April 9 (Reuters) - Hamburg SV recovered from a shocking start when they conceded a goal after just 35 seconds to beat Manchester City 3-1 in an action-packed UEFA Cup quarter-final, first leg on Thursday.

Martin Jol's team, who are also chasing the Bundesliga title, were rocked when Stephen Ireland put the visitors ahead almost straight from the kickoff after a smart interchange with Robinho.

The home side equalised when Joris Mathijsen powered in a header from a corner after nine minutes and took the lead in the 63rd with a Piotr Trochowksi penalty for handball by Micah Richards.

Substitute Paolo Guerrero gave Hamburg a two-goal advantage to take into next Thursday's second leg in Manchester when he slammed in their third from close range in the 79th minute.

"We'd like to forget the first minute, but then after that we played well," said Jol.

"It was a big wake-up call, but we played well in the first half and had five or six great chances and we could have been three or four up by the second half," he told ITV Sport.
