23-year-old Patrick Bamford ended his five-year spell at Chelsea on Wednesday when he sealed a move to Middlesbrough.
Despite failing to make a single appearance for Chelsea, Bamford has refused to rule out a return to Chelsea in the future.
“It was a sad day knowing that I was going to leave Chelsea but it was also probably one of the happiest days of my life as well,” Bamford told talkSPORT.
“I was so happy to come back here to Middlesbrough.
“I’ve put Chelsea behind me now but I really enjoyed working with the staff and the players there. I’ll remember my time there fondly.
“But I’m not closing the door on Chelsea. You never know what will happen in the future, depending on how well I do.”
