Charlie Appleby believes Expressiy will have little trouble in adapting to racing on a dirt surface for the first time in the UAE 1000 Guineas Trial at Meydan on Thursday.
The daughter of Siyouni takes on 13 rivals in the seven-furlong conditions event, on her first start since finishing third in a Listed contest at Newbury in October.
The Newmarket trainer said: "She takes a nice level of form and experience into the race. It is her first time on this surface, but she looks as though she has got the right running style for it."
Appleby continued: "She was impressive when she won at Chelmsford and ticks a couple of boxes for this race.
"On the back of that Newbury run, she goes in as the highest-rated horse in the race and I am happy with how she has been doing things."
Karl Burke feels Line House will be suited by the track after being heartened by her second to On The Warpath at Southwell last month.
"I think she's a ready-made dirt horse. She ran very well at Southwell, which is the nearest we've got to American dirt in the UK," said Burke.
"She's in great form and we're expecting a good run. Whether she's quite good enough, I don't know, but I think she'll run very well."
The Middleham handler is also looking forward to saddling Born To Be Alive in the Mubadala Global Trophy Handicap.
The four-year-old was twice placed in Listed company last turf season and is race-fit from a run at Wolverhampton on Boxing Day.
"He's in great form. He's really well and, all things being equal, he should run a big race," said Burke.
The Appleby-trained Salsabeel has his first start since finishing down the field in last year's French 2000 Guineas when he tackles the Global Foundries Semi Conductor Trophy.
"He has not been out since the French Guineas, as he met with a setback after that. We then gelded him and it was the plan to come to Dubai," said the handler.
"Obviously he has had the layoff and he is entitled to come forward for the run. He showing all the right signs and is ready to run.
"He was beaten by Beat The Bank at Newmarket in April and hopefully he can bring that form to the table."
Evergreen nine-year-old Baccarat is one of two representatives for the Newmarket handler alongside Van Der Decken in the Cleveland Clinic Abu Dhabi World Class Healthcare Cup.
Appleby said: "Old Baccarat is a seasoned campaigner out there now who always runs his race. As he is a hold-up horse, he just needs the rub of the green. He just needs the gaps and nothing to get loose.
"We are dropping back down to six with Van Der Decken and we are on more of a fact-finding mission with him.
"He has run a couple of nice races out there on the dirt before. He has plenty of toe, but he has not been straightforward."
