Celtic's dominance in the Scottish Premiership continues, with the Hoops sitting 3 points behind leaders Heart Of Midlothian. The team has scored 59 goals this season, conceding 35, and is set to face Motherwell at home on December 26. However, former Celtic star Patrick Roberts has a warning for Dan Neil, who recently joined Rangers from Sunderland. Roberts, now at Birmingham City, spent two-and-a-half years at Celtic, claiming three titles and back-to-back Trebles. He revealed that he had a chat with Neil before the transfer and warned him that it could be tough in the city if Rangers don't win every week. Roberts told The Scotsman, "I had this conversation not long ago when Dan Neil called me. He wanted my opinion on the Scottish league, and the city, because it was a similar situation to when I went. I had it very easy. I told him 'you have to win games', then you get the luxury of going out, and you get more confidence and more belief. It can make you feel like you're an absolute superstar when you're performing well [at Celtic]. But when you're on the other end...I didn't get it a lot, and the Celtic players didn't get it a lot. We didn't lose a game in that whole season. Rangers fans couldn't really say anything to you because they had nothing to back it up. But I can see it would be tough if you're on the other side. I played with Waggy [Martyn Waghorn] at Derby, and it was quite tough for him, and quite a few of the Rangers players.
