Arsenal manager Mikel Arteta praised the mentality of Gabriel Martinelli after he hit the headlines for the right reasons -- by scoring a hat-trick in their 4-1 FA Cup third-round win at Championship strugglers Portsmouth.

Guéhi, described as a 'superstar', would be brought in to challenge Gabriel Magalhães for the left-sided centre-back position, while William Saliba and Cristhian Mosquera provide options on the opposite side. Arsenal are also monitoring Valentino Livramento of Newcastle United, highlighting a broader strategy to future-proof their defensive unit.

Havertz returned to the bench for the first time since August last Tuesday but missed the trip to Bournemouth on Saturday.

Liam Rosenior may be looking to prove the doubters wrong at Chelsea but Mikel Arteta says that has never been his motivation as Arsenal boss. Chelsea host the Gunners on Wednesday night in the first leg of the Carabao Cup semi-finals, in just Rosenior’s second game as manager.

Newly installed Chelsea coach Liam Rosenior has rejected the notion that Arsenal was “taking the game back in time” by focusing heavily on set plays under Mikel Arteta.

Liam Rosenior said he has already prepared his Chelsea side for Arsenal's dead-ball threats, despite not agreeing with the nickname "Set-Piece FC" given to the North London side.
