Chelsea paid £23 million to bring Marcos Alonso to Stamford Bridge from Fiorentina during the summer.
Alonso has impressed in the left wingback role and the defender revealed Chelsea winger Pedro has helped him settle in at Stamford Bridge since his arrival last summer.
“Pedro is a very good friend and I like to catch up with him after training,” Alonso told Chelsea official website.
“I didn’t know him before I came here but he’s been a great help since I arrived.
“We go for dinner quite regularly and we went to the NBA at the O2 together. I’m not a massive basketball fan but I follow some of the Spanish players.”
