Celtic misfit Patryk Klimala feels the club may regret selling him as he tears things up across the pond for New York Red Bulls.
The 23-year-old moved to Parkhead in January 2020 in a £3.5million move from Jagiellonia Bialystok but struggled to make an impression.
He appeared just four times for Neil Lennon 's side that season and after four goals in 17 games - most of which came from the bench - he was sold to MLS in the summer.
And while things didn't work out in Glasgow, the Polish youth international believes he improved in the Premiership and is now playing at a higher level.
Klimala said: "I think many people at Celtic are surely now aware how much progress I have made.
"I think that in retrospect I chose well. Celtic were a team playing attacking football all the time, and I saw myself being a part of that.
"But there were also a number of unfortunate situations that resulted in me not playing. There was a pandemic and a few transfers of players from the club did not take place.
"I took up the challenge anyway. I wanted to compete for a place.
"I learned from better players at Celtic. I came from Białystok as a raw player, At Celtic, I gained experience and knowledge. I feel like my time at Celtic prepared me to play at a higher level.
"At Celtic, I improved my physical condition. There, the game is fast and based on physicality. Even before the quarantine, I made a decision that I needed to improve and with the help of the coaches, I did.
"One of the main reasons I went to the USA was game time. I missed that a lot. I was frustrated, which is why I made this decision with a snap of my fingers.
"I knew that there would be a greater chance for development here. For now, I think it has been a good move.
"In my humble opinion, MLS is a better league than the Scottish league and many scouts from all over the world come to the USA to look for talent."
