UPDATE 1-Soccer-Goalless draw leaves Newcastle deep in trouble

(Adds quotes, details)

* Goalless draw of little help to Newcastle

* Shearer without a win after four matches

By Mike Collett

LONDON, April 27 (Reuters) - Newcastle United were left deep in relegation trouble after being held to a goalless draw at home to Portsmouth in a tense Premier League match on Monday.

With four matches left to play, Newcastle remain in the drop zone with 31 points, although the draw was enough to move them ahead of Middlesbrough on goal difference and up to 18th place.

The two north east rivals have 31 points from 34 games, three behind Hull City in the safety of 17th place. West Bromwich Albion are bottom with 28 points.

Interim boss Alan Shearer has now seen Newcastle draw two and lose two of his four matches in charge and many of the home fans left at the final whistle booed their team off the field.

"I am very disappointed not to have won the game," Shearer told Setanta Sports afterwards.
