Stoke returned to winning ways in the Premier League with a 2-0 victory over United at the Britannia Stadium.
Bojan put the Potters in the lead in the 19th minute, and Marko Arnautovic made it 2-0 on 26 minutes with a stunning effort from 25 yards.
Pacheco, currently on loan at Alaves from Real Betis, started his professional career at Liverpool and played for the Merseyside outfit until 2013.
The 24-year-old, who can play as an attacking midfielder or as a winger, played with Bojan at Barcelona’s youth academy and was delighted with the Stoke forward’s goal against United.
