The most important facts about this match are:
1. Czech Republic will be host
2. The match will be played on clay court
3. Serbia is without best player of the world Novak Djokovic
But despite all the above, Serbia is not underdog in this Quarter-Finals. IMO they are maybe a slight favourite. So, everything above even is value from my angle, especially these 2.62 at Bet365.
Czech Republic players: Tomas Berdych, Radek Stepanek, Lukas Rosol, Frantisek Cermak.
Serbia players: Janko Tipsarevic, Viktor Troicki, Nenad Zimonjic, Ilija Bozoljac
The previous time when these two teams met each other was in season 2010, Semi-Finals played in Belgrade, Serbia. Serbia was better back then (3-2) and they later even won the trophy. There is no Novak Djokovic this time in team of Serbia, but still Serbs IMO can achieve three wins. If we compare current situation with 2010 then we will notice that Janko Tipsarevic improved a lot. Since a few days Tipsarevic is the eighth player of the world. This is still weaker result from Czech number one since Berdych is on 7th ATP position. But IMO without any doubt Tipsarevic is the player in best form among all present and he is player who can beat both, Berdych and later also Stepanek. With his two wins the job would be almost done since I rate Serbian double as better. But let's assume that Tipsarevic will have 1-1. Then with win in double, Serbia will need something from Viktor Troicki. He is the weakest link in Serbian team. Unlike Tiparevic, Troicki is not good as he used to be. Not so long ago he was also candidate to enter Top 10, but instead he is only at 27th ATP position at this point. Against Top 10 players Troicki has bad run and this losing streak goes on almost 20 defeats in a row. But if Troicki can't beat Berdych he surely can beat Stepanek (24th on ATP). The good news is that Stepanek was successful in USA couple days ago and from that reason he was late to join the National team. This veteran is probably tired now and he had less time than others to adjust to the new surface. About Berdych is all well known. He can be almost equally good as on hard court as well on this clay court. The hosts have big hopes in him but from my angle Berdych is not even close to his best form.
Head to Head among the players:
Berdych vs Tipsarevic (4-4 overall, never on clay, 2-2 in 2011, Tipsarevic won 3-1 in the above mentioned Davis Cup SF in 2010).
Berdych vs Troicki (2-1 overall, never on clay, the most recent meeting June 2011).
Stepanek vs Tipsarevic (1-2 overall, once on clay - Stepanek, no recent meetings-2010 the last one).
Stepanek vs Troicki (4-2 overall, never on clay, no recent meetings-2010 the last one).
So, according to this I would say that hosts were too much optimistic when they chose clay surface. There were not head to head among these players on clay court, especially not recent head to head, so I doubt that surface will be advantage for hosts. Serbian players are known as good on both, hard and clay. Of course for both, Tipsarevic and Troicki hard court is the main surface but the same and maybe even more is when we talk about Berdych-Stepanek.
Advantage of home court also should not be crucial. Of course that Arena will be crowded but in tennis this does not mean too much. On the other hand, referees can always help to home team since the line referees are from country host. But in this case this is also irrelevant since on clay court every ball leave the mark.
For the end I should say couple words about rest of players who will take part in this quarter-finals in match between doubles.
The hosts have announced that Lukas Rosol and Frantisek Cermak will play for them in second day, but of course that they wont. Berdych and Stepanek will be on the court also on second day. So there is no need to talk about Rosol and Cermak but I should say that Stepanek is good double player, with very solid volleys. Couple days ago he won trophy in Miami in doubles. But I still think that Serbian team have advantage there. Nenad Zimonjic is one of the best players of the world in doubles. And not just now but few years already. Like the hosts, Serbia also announced false information that Zimonjic will play in pair with Ilija Bozoljac. Of course that Bozoljac wont be on the court but one of the duo Tipsarevic - Troicki. My opinion it will be Troicki who will join to Zimonjic.
All in all, overall 2.62 is quite good for this bet. Expected result Serbia 4-1. The winner of this match will meet in semi with Croatia or Argentina.
