The Glasgow outfit will host newly-promoted Scottish Premiership side Dundee United when club football returns to action following the international break this weekend.
The Terrors currently sit eighth in the table, having won just two of their six games, but Gers boss Gerrard has been impressed with the confidence and belief they have shown so far.
The 40-year-old pointed out how Dundee United have put up a fight in each of their games so far, including against Celtic, who secured a narrow 1-0 win in the match.
Gerrard is also an admirer of Dundee United manager Mellon, who he is sure will not sit back against Rangers, and expects the visitors to come at his team on Saturday.
“I have been impressed with them“, Gerrard said on Rangers TV.
“I think, barring the Kilmarnock result, where obviously it was a strong scoreline from Kilmarnock’s point of view, I think they have been in every other game.
“I think they have been really close, I was impressed with them against Celtic, they were really close to getting a real positive result.
“[Against] Hibs, they only lost by a goal.
“I think they have come up with confidence and belief.
“They are a team that are used to winning, they are on that wave of success.
“I think they have got a manager, someone who I have watched from afar for a long time, who I don’t think he is going to be a manager that is just going to sit on the edge of his box and go ‘can we try and nick this?’ and come and try and beat us and wait to be beaten.
“I think he is going to come and have a real good go, that’s the evidence that I have seen, so it would be interesting to see how he sets up at the weekend.“
Rangers will be looking to keep their unbeaten run going when the Terrors visit Ibrox this weekend., having won five and drawn one of their six games so far.
