The British Team will be boosted not only by the presence of a certain Andy Murray but also by the recent emergence of an ever-improving Dan Evans.
Combined with a very strong doubles pairing, this makes GB favourites to win this tricky away tie on the red clay in Umag.
GB captain Leon Smith, taking charge of his first away tie, will be delighted to have the Wimbledon champion at his disposal.
Much has been made of the absence of Murray from the competition in recent years, but with the sudden burst of form from Evans, the steady improvement of James Ward along with the choice of four or five genuinely world-class doubles players, perhaps this will be the first of many appearances for Murray in the foreseeable future.
My feeling is that he will feature in all three matches. Having made the trip to Umag and put in close to a week’s worth of preparation, I can’t see a strong enough reason why he won’t play Saturday’s doubles with fellow Scot Colin Fleming.
The art of the captaincy will be to give Murray his own space and perhaps lead him down a path of making that decision himself as opposed to creating an atmosphere where he feels obliged to play all three matches.
We could know the answer to this when the final four man squad is revealed on Thursday.
If Jonny Marray takes the place of James Ward then that suggests there is a good chance that Andy will not play the doubles.
However, if the squad remains unchanged the intention will be for Murray to play on all three days.
What about the Croats? Well, they are playing at home and they have chosen a surface that the Brits are least comfortable on.
Unfortunately for them it looks like they will be without their star player Marin Cilic and big serving Ivo Karlovic.
That leaves them with world number 35 Ivan Dodig to lead the line with the little known Antonio Veic, world number 205, as their number two.
That said, the doubles is going to be as crucial as ever.
We cannot expect Evans or Ward to beat Dodig on day one, which would leave the tie locked at 1-1 going into the doubles.
On paper, there is no question that Great Britain are favourites but Davis Cup tennis can have all sorts of weird and wonderful effects on people, which is what makes this tie such an interesting spectacle.
