Rangers midfielder Ryan Jack has struggled to get his head around the Gers’ performance against St. Johnstone on Saturday after their recent wins over Aberdeen.

The Gers turned over Derek McInnes’ side home and away but looked a shadow of that side against Tommy Wright’s Saints on Saturday afternoon.

Rangers took an early lead through Alfredo Morelos’ third goal in three games before goals from Blair Alston, Denny Johnstone and Graham Cummins secured a surprise win for the Perth side.

Jack admitted he was frustrated with how Rangers stopped doing the right things and allowed St. Johnstone back into the game.

“It’s frustrating again that we go ahead and we have a good start, a bright start with everything we spoke about before the game,” Jack said, as quoted by the club’s official website.

“We come out the traps quick, get the goal and settle everything down, settle the fans down and get them on side and from then on in, from really when we scored, we stopped doing the basics, started forcing things, started playing long balls and we weren’t winning enough second balls. It just wasn’t good enough.

“Everybody talks about momentum and everything is brilliant when you are winning games.

“We beat Aberdeen twice and there’s no doubt we played really well. So how can we turn up against Aberdeen, a double header, play the way we played, pretty much played them off the park at times, and then we turn up today and we are just not at it?”

The Light Blues face Kilmarnock this weekend and will be hoping to get back to winning ways ahead of the looming trip to Celtic Park.

Graeme Murty’s side travel across Glasgow to face Celtic on December 30th and could blow the Scottish Premiership title race wide open with a win over their bitter rivals.

Jack joined Rangers in the summer from Aberdeen after his Dons contract expired and the centre midfielder has been a mainstay in the Gers’ starting XI.

The 25-year-old has been sent off four times this season although two were later rescinded by the Scottish FA.

In other Rangers news, Jim Duffy has urged the Gers to appoint this 59-year-old as soon as possible.
