Boruc first loan was an emergency loan, we could have recalled and I'd be grateful if you post the link to where Koeman said that. His second loan is a long term loan. As Boruc is a goalkeeper we can recall. Rule 6.6.3

I am sure the club want shot of Boruc, but if Fraser breaks a leg February 1st they will suffer him.
