Sanchez blow for Arsenal

Arsenal lost Alexis Sanchez and Laurent Koscielny to injury during a 1-1 draw at Norwich City on Sunday that prevented them drawing level with Premier League leaders Manchester City.

Sanchez set up Mesut Ozil for Arsenal's 30th-minute opener at Carrow Road, but after Lewis Grabban had equalised just before half-time, the influential Chilean left the fray clutching his right hamstring.

Centre-back Koscielny had already departed by that stage, having been replaced by Gabriel in the 11th minute, leaving Arsenal manager Arsene Wenger with eight senior players on the treatment tables.

Defending his decision to select Sanchez, who had complained of a tight hamstring after Tuesday's 3-0 Champions League win over Dinamo Zagreb, Wenger told Sky Sports: "At the moment on the striker front we have not much choice because (Theo) Walcott is out, (Danny) Welbeck is out.

"I would have rested him today, but he felt perfectly alright before the game. He declared that he had no problem."

Wenger also revealed that midfielder Santi Cazorla had finished the game nursing a leg problem and said that he, Sanchez and Koscielny would all undergo tests on Monday.

Sanchez released Ozil to lift a cool finish over John Ruddy, but Norwich levelled when Robbie Brady's incisive pass found Grabban, who rolled Gabriel and slotted the ball past Petr Cech.

Arsenal are now two points below City in fourth place, with Leicester City and Manchester United between them, having squandered an opportunity to move level on points with Manuel Pellegrini's side.
