lennon brands rangers favourites celtic s neil lennon admits rangers could be considered  slight favourites  for the old firm cis cup clash  but insists his side can still win.  lennon concedes rangers are in good form at the moment  but they have failed to beat celtic in their last seven meetings.  rangers are on the up and have been on a good run in recent weeks   he said.  but it s a game we believe we re capable of winning if we play our best   he told the evening times.  all the boys are looking forward to it because they are brilliant games to be involved in.  without playing at the top of our game  we have still been winning matches.  at the minute  we are at the top of the league and still in with a chance of staying in europe  so i don t think it is the crisis people have been trying to make out.  of course  it is a concern when you are losing goals  because we have been notorious for being a team that is hard to beat and keeping clean sheets  but hopefully we are over that wee run.  considering we lost henrik larsson at the end of last season  we have still been scoring a lot of goals  which is pleasing.
