If sanchos happy to sit on liverpools bench he should come barnes issues warning over 100m transfer

I think there may be a few assumptions and wordplay going on here!

To clarify, I'm assuming you're referring to Sadio Mané, a Senegalese professional footballer who plays as a winger for Liverpool and the Senegal national team.

If that's correct, here's a breakdown of your statement:

• "Sanchos happy to sit on Liverpool's bench": This is likely a reference to Sadio Mané, not Sanchos (which doesn't seem to be a well-known footballer). Sadio Mané has been a key player for Liverpool, so it's unlikely he'd be happy to sit on the bench.
• "he should come Barnes issues warning over 100m transfer": This sentence is a bit confusing, but I think you're suggesting that if Sadio Mané were to be unhappy with his role at Liverpool and potentially leave the club, he should warn his teammate, Harvey Barnes, about the potential issues that could arise from a £100m transfer.

To clarify, Harvey Barnes is an English professional footballer who plays as an attacking midfielder for Leicester City. He has never played for Liverpool, so it's unclear why Sadio Mané would need to warn him about potential issues related to a transfer.

If you could provide more context or clarify your statement, I'd be happy to help further!
