I seriously doubt anyone here has that answer. His retirement was called for when he dropped out of top 50 and was losing in qualies, yet he came back and put in some impressive performance and wins since. Can't you just trust the guy to know for himself when he still has something to offer and when it's time to call it a day?
No. No need to retire being ranked No.24 in the world.
Ljubo started the year with R3 at AO, 3rd time in his career and 1st time since 2006.
He had a couple of bad matches, but it should not make him consider retirement.
If he continues playing like this until the end of the summer, then he should think ending career. But right now - no way
