Mark Warburton feels there is plenty more to come from Rangers striker Martyn Waghorn after reaching 25 goals for the season as early as January.
Waghorn contributed a hat-trick in the club's 5-1 win over Cowdenbeath as they secured a place in the last-16 of the William Hill Scottish Cup.
The former Sunderland, Leicester and Wigan striker is the leading scorer in the United Kingdom in all competitions, passing Peterhead's Rory McAllister, but Warburton believes he is yet to produce his best since moving to Ibrox last summer.
He said: "The more often he plays the greater his belief in his ability and he'll get better and better. He's on 25 goals in early January and he will get stronger and stronger.
"Martyn's target was to play football and, as basic as it may sound, to play week in and out. He is a victim of his own success - at 19 he got his £3m move to Leicester and spent time on the bench in the Premier League but he needed to play.
"He's doing that now, developing nicely and there's a lot more to come from Martyn Waghorn.
"He did very well today. He's dealing with the expectation here. He came here as a striker to a club like Rangers and the crowd expect, quite rightly, that he delivers - and he's doing that.
"He needs that to build his own self-belief to recognise how far he can go in the game. I've known him since the age of 18 and have no doubts about his ability and still think he'll get even stronger from here."
Former Rangers favourite Brian Laudrup will conduct Monday's fifth round draw at Hampden but Warburton insists he is not bothered who the Dane picks out.
"We have no preference about who we play next," Warburton added. "It was all about being in the next round, delivering a decent performance, and whoever draws Rangers in the next round will know they face a good game."
You can see the draw for the fifth round at 6.15 on Monday evening on Sky Sports News HQ.
