Unless we can get Dahoud then Wijnaldum and a LB looks like that will be us done for the window. CM and LB aside, I don't think our squad is too bad.
We showed last season we can compete with anybody on our day but we didn't score enough to pick up consistent results. Our lack of goals was a result of terrible luck with injuries to our front players (and not just Sturridge) - Ings missed nearly the entire season and also all of Coutinho, Firmino, Origi and Benteke missed more than their fair share of games through injury too - and a lack of options in the attacking midfield roles. Too often Allen, Henderson and Milner were having to fill in there because we had nobody else. Bringing in Mane and possible Wijnaldum gives us more options and hopefully goals, and touch wood we can't be as unlucky with injuries as last season.
Iinm, in terms of number of days missed through injury Liverpool players were the 2nd most injured last season.
edit: Yep, Newcastle had the highest, Liverpool 2nd and Utd 3rd. Leicester, unsuprisingly had the best injury record:
