The 31-year-old midfielder ended the last campaign in spectacular form to help the Magpies finish 10th in the league, and he has continued his partnership in the centre of the park this season alongside Jonjo Shelvey.
However, many are convinced that the Senegal international has dropped off the pace and hasn't been the colossus in midfield that broke up play so well last season for them.
He particularly struggled on Saturday against relegation favourites Cardiff City, as it was midfield opponent Harry Arter that ran the show during the game and got the better of him.
Rafael Benitez’s side have had a difficult start to their league campaign with a 2-1 home defeat to Tottenham and a goalless draw away to Cardiff at the weekend.
Some Newcastle fans are convinced that Diame should be dropped for the next match at home to Chelsea, suggesting that summer signing Ki Sung-yueng is the ideal replacement in the midfield.
Ki, 29, is a brilliant passer of a ball that has a wealth of experience in the English top flight and will hope to become a regular starter at St James’ Park.
Diame is more of a powerhouse midfielder that does defensive work in front of the back four, while Ki is a more technical player that is comfortable in possession. The South Korean previously performed well alongside Jonjo Shelvey at Swansea City, and some fans are keen for the pair to rekindle that partnership in the North East.
Here's what Newcastle have been saying on Twitter:
Definitely need to give Ki & Shelvey a chance to play together.— Lewis Reay (@lewisreay14) August 19, 2018
Ki & Shelvey know each other well, Diame needs to understand there is competition for his place, now is a good time to play Ki I think— Nathan Fox (@Foxy_005) August 19, 2018
Think Diame needs to be dropped tbh, no matter who comes in. He's been terrible in possession and lost it so many times, Has to be Ki and Shelvey for me. Can't be any worse!— Paul Whyte (@Chalky_Whyte) August 19, 2018
Ki for diame after diame first 2 games his passing isn't up to it at the minutr gives the ball away a lot— Simon Dixon (@SIMONNUFCDIXON) August 20, 2018
Yes. Although Diame’s improvement has been marked, Ki is different class and looks after the ball a bit better. Would like to see him given a start. Early days yet #NUFC— Dean Burns (@deanoburns) August 19, 2018
I want to see Ki play alongside shelvey , Diane gave ball away too much at Cardiff although he did some gd tackling— jimmy kelly (@xskye69x) August 19, 2018
Shelvey and Ki knows each other well from their Swansea days. After Diames performances Ki needs to be starting for now on— Michael (@MichaelNUFC9) August 19, 2018
