Henning Berg remains convinced Blackburn Rovers can be promoted this season, saying: "Our ambition is to go up."
Berg stated an immediate return to the Premier League was the only acceptable target when unveiled as Steve Kean's successor at Ewood Park earlier this month and is unmoved despite failing to register a victory in his first three matches at the helm.
A 2-0 defeat at Crystal Palace was followed by draws with Huddersfield and Birmingham, with Rovers holding the lead both games.
Ahead of Saturday's trip to face strugglers Peterborough, Berg said: "It's a very good squad and our ambition is to go up, there's no doubt about that.
"We just have to make sure that we improve as a team and we take it step by step. I think with the right attitude I think we can be promoted this season.
"All games are hard games in this league. We just have to make sure we have the quality so that we win games instead of drawing."
Burrow, 20, sustained the problem when making a block tackle in the 4-1 victory over Barnet last weekend.
A scan revealed the damage to be more severe than first feared, with the player now set for a spell of 10 to 12 months on the sidelines.
Boss Jim Bentley told Morecambe's official website: "It's a huge blow for Jordan and for us.
"We didn't realise how bad it was at first but then we got the results of the scan and it was worse than expected.
"It is another blow for us as he is the second striker now ruled out for a time with the same injury and it leaves us a bit short of options but we will continue to work hard and assess all our options."
