Joe Cole believes Pulisic will have been left ‘raging’ with the decision.
Chelsea defeated the 13-time Champions League winners 3-1 on aggregate to set up an all Premier League final against Manchester City on May 29.
Timo Werner and Mason Mount scored for Chelsea at Stamford Bridge, having played out a 1-1 draw in Spain with Pulisic scoring the Blues’s only goal last week.
“It surprised me,” Cole said on BT Sport. “Havertz has played himself into it. I think it’s the one where Tuchel would have been sitting there, with Werner, I think he runs off the ball better than anyone in this squad.
