Richard Foster: Ross County re-sign right-back after St Johnstone fallout
Richard Foster says it was "probably best for us both" that he left St Johnstone to re-join Ross County after a disagreement with boss Tommy Wright.
The 34-year-old has signed a one-year contract after being allowed to leave their Scottish Premiership rivals.
Foster was not prepared to go into any detail about the training-ground incident that led to his exit.
"Relationships in football sometimes come to an end and this was certainly one of those times," he said.
"Sometimes in football relationships change and things happen and it is probably best for us both that I have moved on."
Foster had played five of St Johnstone's six games this season but was missing for Saturday's 2-2 draw with Hibernian.
The defender had not trained with the first team since a training-ground incident on 17 August.
"Luckily for me, I have managed to move myself on and get to a club where hopefully I am going to enjoy my football," he told BBC Scotland.
Foster joined Saints from County in 2016, going on to play 112 times for the Perth side and insists he bears no ill will towards anyone at McDiarmid Park.
"I've made friends there, both in the playing squad and the staff around the place, and I wish them every success and I would imagine that they are the same with me," he said.
"Football careers are too short to be bitter or to have regrets, so I think both parties will move on and look for success in our separate ways."
Foster is returning to a club with whom he has good memories, having been part of the County side that won the League Cup three years ago in his 43-game season with the Dingwall outfit after leaving Rangers.
"It is a club where I had a lot of success," he said. "It is a club where my family and my wife enjoyed coming up to support me.
"It is very family orientated here. When the opportunity arose to come back, it was one I snatched at."
Foster, who began his career with Aberdeen and had a year-long spell with Bristol City before returning to Scotland with Rangers, believes last season's Championship title winners can continue their early promise in the top flight.
"They had the bounce back last season and I think they are still carrying a bit of that bounce and a bit of that swagger, which is good," he added.
"Rangers and Celtic apart, I think most teams are going to beat each other, so I think consolidating our position in the league is first and foremost the priority and anything above that is a bonus."
