Hull defender Andy Robertson has 'no doubt ' Chelsea will claim the Barclays Premier League title after witnessing their winning habit first hand . Jose Mourinho 's 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 . Chelsea 's Diego Costa is stopped by Hull City 's 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 . 'There 's no doubt Chelsea will be champions , ' he said . ' I ca n't see past them and to be honest I have n't been able to see past them for a while now . 'If they 're not at their best they have a manager in Mourinho who gets them to grind out results and that 's what they 've done again , that 's the side they are . 'It 's 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 did n't deal with too well , but they ground it out and that 's why they are going to be champions . ' Loic Remy scored Chelsea 's winner minutes after coming on in the second half . Remy 's 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 do n't 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 could n't 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 we 've already picked up points against Arsenal , Manchester City , Liverpool and we 've run Chelsea close twice now , so we take a lot of positives from that . ' A point would have been a bonus but we 're glad nobody else picked anything up so we 've lost no ground . ' Had Chelsea lost points , Thibaut Courtois ' first-half gaffe for Hull 's equaliser would surely have become a bigger talking point . The Belgian goalkeeper inexplicably miscontrolled Branislav Ivanovic 's back pass straight to striker Abel Hernandez , who was left with an open net for his first goal since October . Jose Mourinho 's 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 does n't come , but we do n't say that , ' he said . 'He tried to play , lost the rebound , the defenders did n't 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 . '
