I don't think that's his fault- none of our full-backs attempt it often despite all bar Zinchenko having the right qualities to try it. I think under any other manager all four of them would but I reckon Pep tells them not to unless it's a really clear opportunity.The only negative I had of him tonight was when he had the space to beat the fullback and whip a ball in behind the defence he didn't take it.
For me our LB options at the moment are Zinchenko > Angeliño > Mendy
