Maybe,but im sure they were as surprised and bewildered by the team choice as the rest of us and that cant have failed to have an impact.
After 5 years being under Pep they 1) Shouldn't be surprised and 2) Know he's won them 10x more games than he's lost.
He's actually been an incredibly generous lightning rod for the players over the years. Pep didn't cause Fernandinho to slip over in his box, or stop anyone closing down Oxlade-Chamberlain, but all people talk about is a frankly irrelevant decision to play Gundogan. Pep didn't make Laporte gift Son 2 goals in the first 20 minutes of the Spurs game or miss a penalty, and yet all people talk about is him not risking a half-fit KDB. Pep didn't make Laporte fuck up against Lyon, or miss tap ins.
And he's never blamed them, he's happily let the peanut gallery and the tabloid writers and the talking heads blame him entirely.
Perhaps the biggest problem with Pep making changes in big games is that it's given some players an easy excuse to not turn up, and they've taken full advantage of it over the years.
If any of them do question him, we need to thank the for their service and get rid of them asap, because the one thing that guarantees a tactical plan not working is the players not committing to it 100%.
However, I suspect the players have a better memory than some fans, and the Premier League title they won thanks to Pep's tweaks and unusual selections is probably still dominant in the memory.
