No squeeze can operate unless we can eek out an extra trick in clubs, and the only way that's possible is if RHO has ♣97 or ♣T9. So we have to win trick 1, draw trumps, and play the ♣J from dummy. Win the return, and (assuming RHO plays the ♣7) take a ruffing finesse against LHO's ♣T (if RHO played the ♣9 from ♣T97, he got me). Then all we need is RHO to hold the ♦KQ and six spades to the K, and he will get ♦-♠ squeezed on the run of the hearts.
