UPDATE 1-PREVIEW-Soccer-English FA Cup team news

(Updates first item with Saha fit)

LONDON, Feb 15 (Reuters) - Team news ahead of this weekend's FA Cup fifth round matches involving Premier League teams:

* Manchester United face Arsenal in the match of the round at Old Trafford. United forward Louis Saha has recovered from a cartilage problem and is available for selection, while Wayne Rooney also returns after being suspended for last week's derby against Manchester City.

Arsenal, five points clear of United at the top of the Premier League table, are likely to be without Thomas Rosicky (hamstring) for their fourth FA Cup meeting with United in the last six seasons. Midfielder Abou Diaby is out with a calf strain.

* Holders Chelsea face League One (third division) Huddersfield Town for the second time in the FA Cup in three seasons. They have almost a full squad to chose from after the return of their players from the African Nations Cup and the return to fitness of Frank Lampard, John Terry and Andriy Shevchenko.

* Liverpool's Spanish striker Fernando Torres may not be risked for the visit of Championship (second division) side Barnsley. He is back in training after injuring a thigh playing for Spain last week but manager Rafa Benitez may rest him until Inter Milan visit Anfield in the Champions League next week.

Defender Martin Skrtel pulled a calf muscle in training and is unlikely to play.

* Portsmouth visit Preston North End, who are struggling in the Championship but won 4-1 at Premier League team Derby County in the fourth round. Striker David Nugent, who has struggled to make an impact since leaving Preston for Portsmouth last year, has recovered from a hernia injury and could be in the squad, especially with new signing Jermain Defoe being Cup-tied.

* Two clubs formerly managed by Bryan Robson meet at Bramall Lane where Championship side Sheffield United, who parted company with Robson on Friday, take on Middlesbrough.

Boro's main doubt for the first FA Cup tie between the two clubs for 85 years is Tuncay Sanli (hamstring). (Editing by Peter Rutherford and Sonia Oxley)
