<text>  Hull defender Andy Robertson has no doubt Chelsea will claim the Barclays Premier League title after witnessing their winning habit first hand. Jose Mourinhos men restored their six-point lead over Manchester City with a 3-2 victory at the KC Stadium on Sunday, substitute Loic Remy grabbing the winner after the Blues let an early two-goal lead slip. Relegation battlers Hull pressed hard for an unlikely decider of their own with the scores tied but Chelsea held on and took their chance when it came. Chelseas Diego Costa is stopped by Hull Citys Andy Robertson and Michael Dawson . And for Scotland international Robertson, those are the qualities that will stand them apart at the end of the campaign. Theres no doubt Chelsea will be champions, he said. I cant see past them and to be honest I havent been able to see past them for a while now. If theyre not at their best they have a manager in Mourinho who gets them to grind out results and thats what theyve done again, thats the side they are. Its three more points and a step closer to the title. At 2-2 we were able to press them higher and make chances, which they didnt deal with too well, but they ground it out and thats why they are going to be champions. Loic Remy scored Chelseas winner minutes after coming on in the second half . Remys shot crept past Allan McGregor and over the line to give Chelsea a 3-2 win . The Tigers may not have improved their own position at the wrong end of the table, but the manner in which they took on the front-runners can at least leave them in good heart. They have arguably the toughest run-in of the bottom five, with Southampton, Liverpool, Arsenal, Tottenham and Manchester United still to come, and the ability to compete with the top sides will be a must. I dont think we can fault our performance after going 2-0 down to the soon-to-be champions in the first 10 minutes, said Robertson. Our two strikers had their centre-backs on toast, they couldnt deal with our lads at all. Eden Hazard fired Chelsea into an early lead but they were pegged back by Hull before half time . Hazard celebrates his excellent strike that put Chelsea ahead early on . John Terry and Gary Cahill are two very good defenders but credit to our strikers, they made them look very ordinary. Unfortunately for us their keeper was on great form. If you look at our results weve already picked up points against Arsenal, Manchester City, Liverpool and weve run Chelsea close twice now, so we take a lot of positives from that. A point would have been a bonus but were glad nobody else picked anything up so weve lost no ground. Had Chelsea lost points, Thibaut Courtois first-half gaffe for Hulls equaliser would surely have become a bigger talking point. The Belgian goalkeeper inexplicably miscontrolled Branislav Ivanovics back pass straight to striker Abel Hernandez, who was left with an open net for his first goal since October. Jose Mourinhos side are six points clear at the top of the Premier League . With the benefit of the three points, not to mention an otherwise superb display from Courtois, Mourinho was able to sweep the incident aside. If you tell our goalkeeper every time he has a back pass to kick the ball to the stands the second goal doesnt come, but we dont say that, he said. He tried to play, lost the rebound, the defenders didnt open a passing line to play from the back: goal. Everybody is unhappy, obviously, I am probably the first one. But I told the players at half-time, there is no point now in analysing details and mistakes of the first half. The point is to go back to our football. The first minute of the second half the team went back to quality football, to creation, to movement. I think we deserved to win.
