Rangers ended their pre-season schedule with a goalless draw against West Ham at Ibrox, but suffered an injury blow as Thelo Aasgaard went off with a shoulder problem. The Norwegian forward could now be a doubt for Friday's Premiership opener against Dundee United. Derek McInnes' side showed improvement from their midweek win over St Etienne, with Cammy Devlin standing out in midfield. Rangers finished second in last season's Premiership with 69 points, one behind leaders Heart of Midlothian, and will hope to build on that this term. ## What happened in the match? Rangers created the better chances against West Ham, with Aasgaard and Lawrence Shankland both going close in the second half. The Ibrox side were solid defensively, limiting the Hammers to few clear opportunities. However, their attacking threat remains a work in progress as they prepare for the new campaign. ## Injury concern for Rangers Aasgaard's shoulder injury late in the game is a worry for McInnes, who is already without new signing Vanja Dragojevic due to visa issues. The Serbian midfielder watched from the stands and may not be ready for the trip to Tannadice. With Nico Raskin still sidelined, McInnes has plenty of midfield options but needs his key players fit. ## Devlin impresses again Cammy Devlin continued his strong pre-season form with another standout performance. The Australian midfielder has quickly won over the Rangers support since his debut against St Etienne. His energy and work rate could be crucial as Rangers look to challenge for the title this season. ## What comes next? Rangers will now focus on their Premiership opener against Dundee United on Friday night. McInnes is still looking to add to his squad before the transfer window closes. The Gers will then face league leaders Heart of Midlothian away on October 28 in a key title clash.
