Not a change to our system per se, but adding more strings to our bow gives us more options, not less.
Grealish played very well on Friday. However, in the second half, we broke from an Arsenal attack with Grealish carrying the ball into the centre-circle.
He looked left & right, & there was only Haaland on, but he had 3 players surrounding him, so Jack spun around & passed the ball back into our midfield, giving Arsenal time to get back & reorganise. We need that speed out wide that only a 32 year old Walker provides.
Also, I noticed Jack running centrally & veering over to the left on a few occasions. At some point (possibly in a lower grade home match), we have to try Jack & Phil centrally. For me, neither are the winger we need.
We've a need for speed & even though Foden is deceptively quick, I still think he'll ultimately be better centrally, as would Jack.
