I think Bangladesh. They will bring a full squad and they will provide feisty competition
Won't happen - and no politics here, simple business logic tells that. Going back, 2015 PAK tour to BD was PAK's home series - PCB was reluctant to arrange it in UAE, so it was hosted by BCB and PCB was compensated - case closed.
2017 Series was BCB's home series and it was pre-scheduled, accepted as well. And, that tour had only 3 ODIs (just in case if I take that PCB was hesitant for a loss could have forced PAK to WC qualifiers - even 3-0, doesn't pull PAK down to 9th ranking spot by 30 SEP), 3 T20s & 2 Tests. There was absolutely no reason for PAK to decline that tour - I read, it cost BCB over $12mn.
I know BCB people more than anyone here - these are Awami League crooks, but they are business men, can see the color of money. They'll talk everything against PAK or it's cricket team on media, but would hesitate for a single moment to host PAK, because it comes with sweetener - and BCB smells money better than PCB. For a record, you can check - BCB voted against BCCI in the ICC revenue sharing debate - simple maths was, irritating BCCI is a loss of may be an average 3 ODI every year; but going against ICC means irritating entire cricket world - BCCI won't send it's team every year and sponsors won't fill BCB's pocket to see Shardul Thakurs .....
This is an imbalanced cricket economy where almost every country is bullied by BCCI. One example is IPL - they are paying in total 64 foreigners from 10-12 countries to block 2 months of every cricket (hence drying up media money for every one), and then paying $1.5mn to Unadkot. If you check the IPL payment structure - it's basically pampering few top foreigners (so that they keeps their board in check) and rest are all Indian players. Many IPL foreigners are actually getting less than $100K (less than PSL or BPL) - but, IPL is smart; paying Smith, Warner, Strac, AB, Stokes, Gayles, Maxi, Shakib, Gayle, Pollard, Lynn, Guptil, Williamson, Faf, Kok, Johny, Morgan ....... out of anyone's reach and these players will force their board to keep low profile. Which means, over 90% of IPL salary is kept in IND (& I believe foreigners are paid in INR), but they are keeping over 95% of non Indian players jobless for 2 months.
HOWEVER, I can't complain against that - because of fools like PCB. In this current contest, where apart from ECB, more or less every Board is bullied by BCCI, YOU CAN'T DO ANYTHING THAT RESULTS IN COLLATERAL DAMAGE. Every other board (may be apart from CA & ECB who has tied knots with BCCI for exchange series almost every year), has to maximize whatever they can make playing within themselves. In that environment, PCB's call to cancel BD tour for a silly issue was shooting at own feet.
For 2 months, only 2 BD player will be in IPL, none from PAK - it was quite possible to arrange a 7/8 game series for ODI & T20 in UAE or BD (or even in PAK!!) in a revenue sharing model - money won't have been like an IND tour, but still enough to cover the expenses for a profit, added benefit was game (s) for players, which could have ended in a BD tour of PAK just before or after next PSL. Add to that Junior tours, PSL/BPL series, exchange of A Teams, developments teams, joint player development programs ...
Sadly, it won't happen now, because I know BCB better than anyone - they are not dependent on PAK series be at home or away, no reason for them to cooperate with PCB after that U turn (for PCB's biggest challenge - home tours) - they'll ask PAK for the home series first before any further commitment and Nazam Sethi isn't going to coil his tail to say sorry - Galti ho gaya tha .... so, it's a closed loop - BD & PAK players will enjoy at least 2/3 months paid vacation every year now, when others will be playing against each others and not necessarily against IND only.
At certain point, BCB will have to bend in front of BCCI, because money is sweet and BCB has to run it's operation - no point keeping the highest payer at distant when the closer ones are not cooperating. Knowing BCCI/GoI, I am sure they'll put an unofficial clause of boycotting PAK from BD Cricket, may be including BPL/PSL player exchange - I would have done so for sure, it's a shadow war.
They say, history repeats itself - may be this is not the first time PAK & it's hierarchy set the bed for Indians to sneak in & screw PAK's interest.
I sincerely hope, I am proven wrong here in quicker than I expected.
