Arsenal returned to winning ways with a 3-0 victory over Preston North End in the Carabao Cup fourth round on Wednesday night.
Gunners manager Mikel Arteta made eight changes from the 2-2 Premier League draw against Liverpool last weekend.
Mikel Merino got the nod to start against Preston. He had a brilliant opening half before being replaced by Kai Havertz.
The Spaniard scored his maiden Arsenal goal in the thrilling draw against the Reds on Sunday.
He did not get any clear-cut chances yesterday and was brilliant from midfield with a passing accuracy of 100 percent.
The experienced ace also won 100% of his duels with a couple of successful tackles.
Merino had a difficult start after the international break as he struggled to cope with the high pressing at Bournemouth.
However, he has responded brilliantly over the past few outings where Arteta has played him in a central midfield role.
The experiment of starting him as the number 10 against the Cherries did not work.
The Spaniard has returned to a more familiar position and looks to be finding his best form for Arsenal.
Merino is expected to start in midfield alongside Declan Rice in Saturday’s league game against Newcastle United.
With Gabriel Magalhaes doubtful with a knee injury, Ben White could be asked to partner William Saliba in central defence.
This could see Thomas Partey continue at right-back with Jurrien Timber on the opposite end.
Arsenal are already five points adrift of leaders Manchester City. The upcoming game at St James’ Park is a must-win for them.
