That attack looks way too light for me. Whilst I like Redmond I don't think he'll replace Mane's goals and Pelle's "replacement" Austin will quite likely not be on the pitch at least 50% of the time to convert the creativity and crosses Redmond will provide. Add to that the high likelihood that J Rod will never be the player he was - what if he has another season like last year when he was out for the majority of it and scored zero league goals? - and we are potentially far far too weak. We need another proven striker at least and probably another creative type, two if we lose Tadic which I sincerely hope we don't.
Hopefully and probably the club are still working on bringing another 1 or 2 in (Berahino would do nicely) and have reason to be confident that Austin and Rodriguez' previous injury problems are behind them, but to go into the season with that attacking line up would be a real worry.
