Obviously goals do help, but we goals already in the team. Fernandes, Rashford, Antony, Eriksen, Garnacho, Mctominay, Casemiro have all shown they are capable of chipping in.
Our biggest issue has been no link up play with the striker to help our build up play. Look at our first goal against Fulham, Martials ability to drop in, turn and drive at the defence then play in the runner is so vital to how we like to play.
Would a 30 goal a season striker be nice? yeah of course - but there isn't many of those about. If we can be a more cohesive attacking unit and spread the goals around, that's better than relying on 1 man IMO.
