Cakir is reported to be the subject of a £22m bid from runaway Premier League leaders Liverpool.
Leicester's Lee Congerton was invited to watch Cakir in action against Fenerbache in the Turkish Cup semi-final by Trabzonspor's assistant manager Eddie Newton.
Formerly an assistant manager at Chelsea, Newton worked with Congerton there for five years.
"He is one of the best goalkeepers [Cakir] I have seen in my life," Congerton told Turkish outlet Karadeniz Gaztesi.
"I was wondering who the goalkeeper was that Liverpool offered £22 [€25m] million."
The Blues are reported to be lining up a £20m bid of their own for the Turkish goalkeeper.
Trabzonspor president Ahmet Agaoglu declared Liverpool's offer a few weeks prior.
"There are offers for Cakir, we continue to receive offers. It’s been said Liverpool have made an offer," Agaoglu was quoted as saying by Turkish-Football.
"So a team that [was currently] undefeated in the Premier League wants my keeper. In other words, Liverpool’s goalkeeper is in my goal."
