Motherwell winger Jamie Murphy looks about to play his last game for the Fir Park side when they travel to Parkhead on Wednesday. He missed training on Monday as he was down talking to npower League One promotion hopefuls Sheffield United. Teammate Chris Humphrey feels a move would be a just reward for his form shown so far this season. Murphy has found the net nine times in his last 13 games from midfield and Humphrey believes his friend can improve further. Murphy turned down the chance of a move to Blackpool on the final day of last January's transfer window in order to help Motherwell make it to the Champions League qualifiers. However, his salute to the Fir Park fans following Saturday's 2-2 draw with Kilmarnock looked like a farewell. Manager Stuart McCall expects Murphy to move on after the Celtic game and Humphrey feels his team-mate will go on to bigger things. The Jamaica international said: "I'm sure it will be emotional for him and I'm sure it was emotional for his last home game. But he will be looking forward to it and will want to leave on a high. He has been terrific for the four years that I have been here. I think it's a long time overdue. He has done terrifically well and I wish him all the best. Obviously we will see him for the game on Wednesday but he deserves everything he gets because he has been fantastic. I think he can be unbelievable. He has always had the right head on him to do well and I think he can go on to big things." If he does leave after Wednesday, Murphy has picked a difficult game to offer a lasting impression with Motherwell fans. The Fir Park side have scored just three times in their last 12 visits to Parkhead, although that meagre return has yielded four points. But they sit just six points behind Celtic, who lost 1-0 at Hibs on Saturday following earlier defeats by St Johnstone, Kilmarnock and Inverness this season. Humphrey said: "It's always a tough place to go and you can see past results haven't been the best but form-wise we have been doing really well. I'm looking forward to going there and giving them a right good game. Obviously they lost at the weekend and won't be happy but I'm sure if our heads are right and we play the way we can do, we can give them a good game. We have not been in awe of them, they just have great players and bigger budgets to buy players. So we have to just go there and try and do what the manager wants us to do. We need to redeem ourselves the way we have played against them in the past and see if we can get a good result against them."
