Arsenal boss Mikel Arteta has insisted his side are preparing to go "full gas" against Newcastle United in their Carabao Cup semi-final despite a "disappointing" end to the January transfer window.

The Gunners head into the second leg of the tie facing a two-goal deficit but will not be buoyed by any fresh faces, after the window shut without a new signing being made at the Emirates.

A bid was rejected for Aston Villa striker Ollie Watkins, following injuries to Gabriel Jesus and Bukayo Saka which left Kai Havertz as the lone option up front, while there was also interest in Mathys Tel, Benjamin Sesko and Matheus Cunha, according to Sky Sports.

"We had a clear intention. The window is open to explore the opportunity to improve the squad with players who can do that. We haven't achieved it," Arteta said in his press conference ahead of the Newcastle game.

"We are disappointed in that sense but we are very aware we want to bring in a certain kind of player, we have to be very disciplined in that. I think that we were."
