Yes, we need to keep Sturridge. Why anyone would even consider moving him out of this club is beyond me. He has proven himself time and time again, and we need that talent. I'd be prepared to risk another season and see how he gets on. Even playing 50% of games, he is brilliant and we need that class.
If however (and it's a big if), we bring in an incredible world class talented footballer, and so much so that Sturridge's place is in doubt, then we can consider a future without him.
As it stands, that is highly unlikely and we should not be pushing to get rid, just because of his injury record. What other options do we have? We need to strengthen our squad, and that means bringing in fresh (world class) talent whilst retaining the talent that we have.
