Yes, striker and winger, not two strikers—definitely.
I agree Zubi should help, but the numbers show we have a genuine problem with both getting shots off and getting them in the net. Not all our football issues are flow-on effects.
On the other hand, having another Saka-level goal threat ("Shut him down with two defenders or he'll score") on the pitch would give us a big multiplier—not least to Saka himself.
