Inverness manager Terry Butcher tries to forget St Johnstone thrashing Some of the goals we've lost this season have been inexcusable. We've looked at it time and time again. The gaffer has worked with us at training to try and prevent these things happening. So to come away, especially against a team like Aberdeen with the players they have got, with a clean sheet is fantastic. Aberdeen's Ryan Jack said: "We had a few chances to get something in the end but we shouldn't have got ourselves in that position in the first place. We lacked enthusiasm. The management team did everything they could all week to get us ready for the game. We let them down, the fans down and let ourselves down as well. Turkish forward Nadir Ciftci netted the only goal as Dundee United beat visitors Kilmarnock 1-0. He said: "It was a good ball from David Goodwillie and I took my chance. I could have scored more goals before that. We had a few easy chances but sometimes the harder ones go in. It doesn't matter. As long as you win, that's the important thing. Kilmarnock are still without a win this season and slipped to 11th in the table following the defeat. Manager Allan Johnston said: "It's concerning when you are losing games. We shouldn't be where we are just now. We should be higher up the table. But we are down at the foot of the table and it isn't good enough. We've got to work even harder and we've got to improve - the players and myself. St Mirren manager Danny Lennon believes his team can go on to have a successful campaign after securing their first win of the season with a 2-0 triumph over Hearts. Jon McGinn headed home Conor Newton's right-wing cross at the back post in the 42nd minute and Paul McGowan netted from close range in the 58th minute when Jamie MacDonald spilled David van Zanten's low, driven cross. Lennon said: "Getting back to the little things being faithful to the little things, and working hard, when you do that as a group, you get rewards for the big things. I was under a bit of pressure last year with six straight defeats round about November. We managed to overcome that and turn it around. We managed to lift a bit of silverware and get one or two of the club's best results in their history. We went on to win three games in a row. I certainly believe with that type of performance, that character, that discipline, that hunger, that energy, there is no reason why we can't do it again. Hearts manager Gary Locke urged his team to retain belief that they can get out of their predicament. He said: "One thing we can't do is feel sorry four ourselves. The boys are very down but there is still a long way to go. Sean Welsh is relishing the prospect of leading Partick Thistle out against former club Hibernian at Firhill on Monday. The midfielder came through the youth ranks at Easter Road but failed to make a first-team appearance before his departure in May 2012. The 23-year-old Partick captain said: "It will be a good moment. It's good that the gaffer has made me captain here and I'm looking forward to walking out against the former club that didn't have faith in me and thought I couldn't do this. I'm here to prove everyone wrong. I've done it so far and hopefully I can keep going. Hibernian midfielder Lewis Stevenson believes the Easter Road squad is as strong a pool of players as he has ever played in. He said: "I have been ever-present this season and it would be nice to keep that going but we have got a strong squad and things can change, players are coming back from injuries and everyone needs to be on their toes. I honestly think we've got as strong a squad as we have had since I've been here.
