Former England manager Glenn Hoddle believes Aaron Ramsey will have to adjust his game due to Alexis Sanchez.
With the Chilean international playing more of a central role, the tactician believes Ramsey will have to curb his attacking instincts.
Speaking to SkySports, Hoddle explained: "I think that's a great position for him (Sanchez), because he' can go anywhere on the pitch. With or without the ball.
"With Sanchez just in behind, I think Ramsey will play a deeper role, and he will have to choose his moments a little bit less.
"Sanchez is a player that plays in the pocket and I call him a striker number 10, not a midfielder number 10. A lot of midfield players for Arsenal play as midfield numbers 10s, who like to link the play but don't really get in the box.
"Sanchez wants to with and without the ball, so Ramsey has got to play a bit deeper."
Ramsey, 23, scored two goals at the start of the season for Arsenal, but has not netted in any of his last 10 appearances.
Last season goalscoring was a key part of his game, but with Sanchez active in pressing in and around the penalty box, there is less onus on him to get forward.
With Mesut Ozil in the number 10 role, Ramsey was required to run forward and become an option for the German international to pick out with a pass, or even be a decoy for Olivier Giroud.
Arsenal's attack has suddenly taken a different shape, and Arsene Wenger will have to choose which way he prefers to play when everybody is at full fitness, with Ramsey's game likely to be impacted either way.
