The 21 year old England U20 international joins Graham Barrett at the struggling first division side, and is expected to go straight into their side for the clash with Wolves next week.

Sidwell hasn't appeared in the Arsenal first team yet, but is highly thought of and has already been loaned to Beveren and Brentford.

After missing a few games through suspension (he got himsefl sent off almost as soon as joining them), Barrett has been earning respect at Brighton with his recent performances (a Seagulls fans friend of mine says he was one of only 2 players to come out of their recent thrashing at big rivals Crystal Palace with any credit at all).
