Arsenal fans rage over Mikel Arteta decision as Newcastle defeat damages title hopes

And Arsenal crashed to defeat, with Alexander Isak netting the only goal of the game in the 12th minute.

The Gunners seemed to lack a creative spark throughout much of the match, with Martin Odegaard currently sidelined through injury.

And though Arteta did eventually throw on Nwaneri, many fans were unhappy that it took so long.

"I still don't understand why Mikel Arteta doesn't start Ethan Nwaneri," fumed one user.

A second raged: "Arteta needs to understand that Thomas Partey isn't a right back. He needs to understand that Trossard does absolutely nothing better than Ethan Nwaneri on the bench."

Another said: "Arteta is too stubborn. No creative player on the pitch while you have Ethan Nwaneri on the bench."

A fourth hit out at Arteta by saying: "What did Arteta give as the reason for not playing Nwaneri?"

And a fifth said: "We’ve been so much better since Nwaneri came on, but Arteta will see this and still start Trossard over him next game."

Arsenal are currently five points behind Manchester City at the top of the Premier League table.

But that lead will likely be extended if City get the better of Bournemouth later today (3pm).
