First of all -> he is not a winger, it's like Pep was playing Bernardo as a RW and finally (after 19 / 20 season`s failure) - it was clear for everyone that it's not gonna work and he belongs to the midfield. Then he had to play Bernardo as a RCM again (after KDB`s injury) and we all experienced old, prime Bernardo - which led to the 4-month-winning-streak..
That never happened though. Here are the Premier League results for that 14-game winning run in 18/19:
City 3-1 Arsenal: Bernardo played right wing (Midfield of Gündogan, De Bruyne, David Silva)
Everton 0-2 City: Bernardo played right wing (Midfield of Fernandinho, Gündogan, David Silva)
City 6-0 Chelsea: Bernardo played right wing (Midfield of Fernandinho, Gündogan, De Bruyne)
City 1-0 West Ham: Bernardo came off the bench for Sané
Bournemouth 0-1 City: Bernardo played right wing (Midfield of Gündogan, De Bruyne, David Silva)
City 3-1 Watford: Bernardo played in midfield with Günogan and David Silva
Fulham 0-2 City: Bernardo played right wing (Midfield of Gündogan, De Bruyne, David Silva)
City 2-0 Cardiff: Bernardo didn't play
Palace 1-3 City: Bernardo came off the bench for David Silva
City 1-0 Spurs: Bernardo played right wing (Midfield of Gündogan, De Bruyne, Foden)
Rags 0-2 City: Bernardo played right wing (Midfield of Fernandinho, Gündogan, David Silva)
Burnley 0-1 City: Bernardo played in midfield with Günogan and David Silva
City 1-0 Leicester: Bernardo played right wing (Midfield of Gündogan, David Silva, Foden)
Brighton 1-4 City: Bernardo played in midfield with Günogan and David Silva
Bernardo started in midfield just three times.
EDIT - I don't know if you were referring to the winning streak in 18/19 or 20/21, so apologies if you're talking about last season. But I think the point still stands that Bernardo has excelled on the right of the front three for us just as often as he has in central midfield
