Paul Dummett is back on loan with St Mirren but knows he will have to fight for a place now that his team-mates have won the right to appear in the Scottish Communities League Cup final. It didn't look as if Dummett would be returning from Newcastle until his parent club allowed a loan move on the last day of the transfer window. Dummett returned to Newcastle before Saints beat Celtic to reach the final and delivered a 2-1 SPL win over high-flying Inverness. Dummett knows he cannot expect to walk back into the first team for today's home Scottish Cup fifth-round game against St Johnstone. Dummett said: "Some players will probably go through their career without playing in a cup final and I'm only 21. I'm desperate to get back in but Graham Carey has been playing left-back and I can't expect to come straight back in the team. He has done a brilliant job. But that's what is good about the team, having players that can play in different positions and there is going to be a fight for places and that can only help St Mirren get better results and climb up the table." Dummett played in 19 game in his first spell in Paisley and made his Newcastle first-team debut as a half-time substitute in the 2-0 FA Cup defeat by Brighton. Despite this chance, he was always keen to return to Scotland. He said: "I'm very happy because I came here and played a lot games. When I went back to Newcastle I played 45 minutes for the first team and I haven't played a reserve game. I feel playing week in, week out is the better alternative to progress my career. A lot of people do think it's not the best league but I can assure any young player that they can come here and improve. I've played Celtic two or three times and they are in the last 16 of the Champions League. This league is a good league." Dummett feels his improvement was recognised when Alan Pardew gave him a run-out against Brighton. He said: "He didn't have to put me on in that game, there were a couple of other players on the bench that I thought might have got on ahead of me. He showed faith to put me on there. Maybe he had reports back saying I had done well here. I know it wasn't a good result but I don't think I did myself any harm coming on in that game." There could be a meeting with one of his Newcastle teammates for Dummett and fellow loan player Conor Newton after midfielder Mehdi Abeid moved to Perth on transfer deadline day. Dummett said: "He's a good player. Conor and I know him well and we're looking forward to playing against him He has been brought in from France but he has been at Newcastle for two years now." Newton's arrival this month, coupled with the return to fitness of Kenny McLean, allowed Saints manager Danny Lennon to agree a loan for midfielder Jon Robertson with Cowdenbeath. Lennon said: "He is out for a month and by no means are we looking to chase Jon away. He has still got a big, big part to play. I told them if there was any doubt, 1%, don't go. Where we are sitting in terms of depth of the squad, he sees himself slightly on the outside, but we know how quickly that can change. Jon is going there for the right reasons, to get game time, and he is developing at the pace we thought he would. In the absence of Kenny McLean, he came in and did terrifically well."
