Two weeks of pent-up angst erupted during a full-throttle training game as England prepared to take out their frustration on Scotland . Defeat in Dublin in their last RBS Six Nations outing led to a prolonged post-mortem and fostered collective unrest , which came to a head three days before their next fixture , at Twickenham . The desire to produce a backlash in the Calcutta Cup encounter led to a feisty 15-a-side match at England ’ s HQ on Wednesday , overseen by Test referee JP Doyle . England head coach Stuart Lancaster instructs his squad during a training session on Wednesday . The England squad played out a fiercely committed training match on Wednesday ahead of facing Scotland . Head coach Stuart Lancaster said afterwards : ‘ I had to calm it down , blow the whistle at the end and make sure we didn ’ t play the game too early. ’ He was delighted by the players ’ commitment and the calibre of opposition provided to a Test XV featuring two changes — with Mike Brown and Courtney Lawes recalled , as reported by Sportsmail . ‘ The ( non-starting ) pack was Mako ( Vunipola ) , Tom Youngs , Kieran Brookes , Parling , Kruis , Easter , Wood and Kvesic — who came in today as cover , ’ said Lancaster . ‘ You can see the quality of the players who were training against the starting XV .

Mike Brown , who suffered concussion against Italy , is back in the starting XV for England on Saturday . Bath 's Sam Burgess impressed head coach Stuart Lancaster as he took part in England training . ‘ Both sides had an edge about them . The non-XV , if you like , had a point to prove but also wanted to create some intensity in the session , particularly at the breakdown , to make sure we were accurate as a team . ‘ They did that and were a huge challenge for us defensively . We had talked in the review of the Ireland game about being accurate at the breakdown and sharp . Those components came into play and it was the type of session you need sometimes in the lead up to a big game. ’ Asked if the coaches sought to nurture the needle which was in evidence yesterday , Lancaster added : ‘ You look for it , and the players were in the right place for today . I ’ ve been in training weeks where it ’ s been like that — and you have to make sure that translates to match day . The England players played out some pent up frustration during a bruising training session . England : M Brown ; A Watson , J Joseph , L Burrell , J Nowell ; G Ford , B Youngs ; J Marler , D Hartley , D Cole , D Attwood , C Lawes , J Haskell , C Robshaw ( capt ) , B Vunipola . Subs : T Youngs , M Vunipola , K Brookes , G Parling , T Wood , R Wigglesworth , D Cipriani , B Twelvetrees . ‘ We wanted to put the starting team under pressure so that they get used to making decisions under pressure and the more you can replicate that in training , hopefully when the game comes around , it comes easy. ’ Lancaster conceded that England needed to clear the air with a no-holds-barred session . What he also needed was to see some of his fringe squad operating at that intensity , so he paid close attention to Exeter centre Henry Slade and Bath ’ s cross-code recruit Sam Burgess . Lawes has been reinstated in the second row at the expense of George Kruis and he confirmed that training yesterday had been combative . ‘ It was tough , ’ said the Northampton lock . ‘ The boys were certainly up for it , which is what you want going into a game like this . You need to be on edge . It showed out there that we were certainly up for it at the weekend. ’ This is not music to Scottish ears . England have been stewing , they are wound up and desperate to right the wrongs of Dublin . They ’ ve scrapped it out among themselves , now they ’ re primed to tear into Vern Cotter ’ s strugglers . Exeter 's Jack Nowell concentrates as he works hard in preparation to face Scotland at Twickenham . England captain Chris Robshaw ( centre ) talks to his team-mates during a break in training .

Stuart Lancaster 's side were beaten 19-9 by Ireland in their last match . England will need to win if they want to keep up with the Six Nations rivals . Scotland have lost all three Six Nations matches so far the weekend .
