Tottenham were too quick to sell "perfect" Swansea talisman Gylfi Sigurdsson says the London club's boss Mauricio Pochettino
Pochettino took over in the summer of 2014 and allowed Sigurdsson to join Swansea in a deal that saw Ben Davies and Michel Vorm move in the opposite direction.
Spurs host Swansea on Saturday.
"I think after he moved to Swansea and we saw his development he was a perfect player for us," Pochettino said.
"It was the club decision and his decision to move to Swansea."
Sigurdsson has five goals already in the current campaign and Pochettino says the Icelandic midfielder is still well thought of at White Hart Lane.
