Jim Jefferies has told his Hearts side to build on their display against defending champions Rangers in Sunday's SPL clash with Dundee United.[LNB] The Jambos host United at Tynecastle after drawing 1-1 at Ibrox last weekend and 1-1 in their Europa League third qualifying round first-leg fixture with Paks on Thursday night.[LNB]Jefferies told Hearts' official matchday programme: "The secret is if you pick up points against the Old Firm then you have to handle everybody else right.[LNB]"United had a tremendous season last time and pushed us close for third place.[LNB]"They have lost one or two (players) but have recruited well, a bit like ourselves, and this is going to be another tough match.[LNB]"We are coming into the game off the back of a European tie in Hungary which is never easy but we just have to handle it.[LNB]"United might have been in the same boat but were unfortunate to go out to a decent side.[LNB]"This will be another tight match and both teams will be eager to put on a good show.[LNB]"Hopefully we can follow up the good work from Ibrox and take another confidence boost by producing most of the form we showed against Rangers."[LNB]David Obua scored as Hearts took a first-half lead at Rangers, who levelled in the second half to deny the capital club all three points.[LNB]Obua's goal came from a Danny Grainger corner and the Ugandan revealed he was acting under the instructions of Hearts goalkeeper Marian Kello.[LNB]Obua said: "We were trying to find a way of beating the zonal marking and Marian told me I should take up the position I scored from.[LNB]"He insisted it was a good position to come in from and attack the ball and to be fair to him that is what happened.[LNB]"It was great to see it go in and while we could have won the game I'm pleased we got a point in the end."[LNB]Meanwhile, striker Kevin Kyle, who has been out since January with groin/hip problems, is targeting a return in the August 28 Edinburgh derby with Hibernian.[LNB]He said: "I've pencilled in a wee game against Hibernian at the end of August, so that would be ideal - perfect really - if I was back for that one.[LNB]"If I could come on and do what I do best, score a last-minute winner, then I'm sure everybody would be happy with that and hopefully forget about the last six months."
