After three matches against top six rivals in the space of ten days, Tony Pulis is expecting a similarly difficult test against Blackburn Rovers on Sunday (kick-off 1pm).
Pulis says it's a positive sign that Boro were disappointed with a four-point haul from those fixtures, and he's targeting a further three against Tony Mowbray's Rovers side this weekend.
"We're disappointed to only get four points and that says a lot for the team," he said.
"We should have beaten Leeds at home with the opportunities and the chances we had.
"And I thought we controlled the game at Bramall Lane in the first half one it settled down. Dani [Ayala] gets sent off and Aden Flint's injury means they can go very direct. If Flinty's playing I think we deal with that.
"[The squad] is a little bit fragile for this one to say the least but it happens and you have to get on with it."
The current Boro manager has again paid tribute to his opposite number ahead of their second meeting of the season.
"Tony is a Middlesbrough legend," Pulis said.
"He was a great player for this football club and he came here for two or three years as manager, clearing up quite a mess.
"I don't think you get the credit digging in and seeing it through. Hopefully people will now reflect on that situation and that time and realise that Tony was up against it, and actually did a very good job in a lot of respects.
"He made three or four changes on Wednesday night, and I can understand the reasoning with so many games in the last couple of weeks.
"We think he's left three of his best players at home, not played them, so they will be up and raring to go against us.
"We know its going to be a tough test and we'll go there and give it our best."
