We don't need anymore attackers, we've added 2 to a strong forward line anyway, with Ings also coming back so make that 3.
Defence was our problem last season and still is, we need to get that sorted asap and before we do anything else.
While I agree that our defence is a big problem, I disagree that we don't need to add another quality attacker.
If you look at just the amount of goals we scored then it seems like we don't have any problems up front. But in reality we score a lot in the games we win but dropped a lot of points in other games simply because we don't have a quality striker. These are the players who will make the difference when teams are "parking the bus" and we fail to break them down. That's why when we had Suarez we scored a lot of goals as well as a lot more points on league table.
Ideally I would like to see us sign a top class striker and Firmino play just behind him as a No.10 with Mane and Salah on the wings.
