  Play the ♠4.

You cannot see the ♠5.
The most likely reason is that East has it, and his ♠7 is an encouraging signal.
The only reason he would encourage you is if he held either the ♠A or ♠J.

Together, you two continue to play ♠s to drive out South's ♠A.
When you get the lead with your ♣A you will cash your ♠ winners and East will still have the A for some icing on the cake.

There IS another possibility if South is a better than average Declarer.
East just might hold ♠ 9 7, giving South ♠ A J 8 5.
South played the ♠8 as a falsecard to tempt you into playing the suit again.
This isn't too likely, but if it happens just congratulate South for the fine play.
