Celtic manager Brendan Rodgers
The Scottish Sun has claimed that having secured Sinclair's signature, Brendan Rodgers will now turn his attention to signing a new goalkeeper.
The Scottish Sun reports that it is an injury to Craig Gordon's understudy Logan Bailly that has persuaded him to look for another stopper.
Rodgers has seemingly quashed any talk of Charlie Mulgrew earning a new deal at Celtic, having told The Scottish Sun that the defender is being allowed to train with the club simply to allow him to keep fit.
The Scotland international's contract at Parkhead came to an end earlier in the summer, but Rodgers has largely dismissed the notion that a new deal could be on its way.
"His contract was up, he was looking to negotiate with the club and unfortunately those negotiations stalled," he told The Scottish Sun.
"He's without a club and he asked if he could come in and train for a few weeks until something happened further down the line."
Rangers manager Mark Warburton
Warburton was the manager who brought Gray, who is now preparing for a season in the Premier League, back out of non-league football, and Gray believes that his old boss deserves some recognition south of the border.
"I don't see why he can't make it to a big English club," he told the Mail.
The striker limped out of the game with 10 minutes to go, and Warburton initially suggested that it was too early to predict how long he would be out for.
"We will need to see how he is, but it looks like a hamstring injury. He is being treated but we will need to see how he presents in the morning," he told the Evening Times.
"We're really disappointed. We felt as if we dominated the game, but Waggy going off at the end killed our momentum. We still created quite a few chances with 10 men, and still looked likely to go on and win, but unfortunately we couldn't do it," he told the club's official website.
