UPDATE 2-Soccer-Liverpool twice come from behind to beat Havant

(adds Chelsea win)

By Mike Collett

LONDON, Jan 26 (Reuters) - Mighty Liverpool were given the fright of their lives by tiny Havant & Waterlooville before beating the non-league side 5-2 in an astonishing FA Cup fourth-round tie at Anfield on Saturday.

The part-timers from Hampshire, six divisions and 123 places below Liverpool in England's football pyramid, twice led against the seven-times FA Cup winners.

But a hat-trick by midfielder Yossi Benayoun denied Havant the biggest upset in the competition's 137-year history.

Holders Chelsea reached the last 16 with a 2-1 victory at Wigan Athletic while Arsenal won the other all-Premier League tie, beating Newcastle United 3-0 at the Emirates Stadium.

Premier League clubs Middlesbrough and Portsmouth also advanced but Derby County were crushed 4-1 at home by Championship (second division) strugglers Preston North End.

Only eight Premier League sides are still left in the competition, with at least one certain to be eliminated after Sunday's Manchester United-Tottenham Hotspur tie.

If Manchester City lose at Sheffield United on Sunday, only six top-flight teams will be in Monday's fifth-round draw.
