LEYTON Orient punish mistakes and they’re ruthless – that was Ben Garner’s warning to Swindon Town ahead of Tuesday night’s League Two encounter between the pair of promotion chasers.

Fourth-place Town travel to eighth-place Orient knowing Kenny Jackett’s team has netted at least four goals in three of their past six league and cup matches.

Orient have the fifth-best home record in League Two while Town’s form on the road is unparalleled – a pair of statistics which promises a tight but fascinating affair.

One of the key reasons for Orient’s impressive home sequence, according to Garner, is down to their cut-throat ability to turn opposition mistakes into goals.

In Friday’s pre-match press conference, Garner said: “They’re a team which punishes mistakes and a team which is ruthless, so we’ve got to be very good with the ball.

“They press well, but we need to be brave and play our game, and try and expose spaces that they perhaps leave behind that press.

“Our concentration levels have certainly got to be very, very high, and our defending from throw-ins and set pieces has got to be very, very good.

“In some ways, there will be aspects of the game which will be similar to when we played Sutton away.

“But Leyton Orient are a very good side, so we’ll have to be right on the money to go there and win – but we’ve got the capability to do that.”

Garner believes Town’s defence will be tested in a variety of ways on Tuesday night, from counter-attacks to long throw-ins.

Swindon have not always dealt with set-pieces particularly well this season, but Garner is of the opinion that his team has greatly improved in that regard and has no concerns over their ability to stay strong once again at Brisbane Road.

The Town boss said: “From two or three games into the season onwards, we’ve generally done well from set-pieces.

“Our set-up has been good, our organisation has been good, and we’ve only conceded one since then. That was a lapse in concentration, it wasn’t anything structural or tactical.

“We need to stand up and be counted, we need to be competitive and on the front foot, but we need to have really high levels of concentration.

“They’ve scored lots of goals on transition this season, probably as high as anyone in the league.

“If you make mistakes, they punish you, so we need to make sure our focus is at its highest possible level on Tuesday night.”
