Liam Rosenior confirmed an injury was behind Marc Cucurella's half-time substitution against Leeds United and gave his view on the moments which saw all three points slip away from us at Stamford Bridge on Tuesday evening.

It was a frustrating night for Rosenior and the Blues, as we took a two-goal lead over Leeds only to see it slip away and leave us with just the solitary point to show for our efforts at the final whistle.

Adding to the disappointment was the withdrawal of Cucurella during the half-time break, and our head coach confirmed after the game that substitution was caused by an injury.

'Unfortunately at half-time he felt his hamstring,' he explained. 'It wasn’t a tactical change, it was one that was enforced.

'Cucu’s been top and hopefully he’ll be okay. We’ll scan him and make sure we find out if he’s available for the next game.'

It had initially looked like being a good night for the Blues, when Joao Pedro and Cole Palmer combined twice to put us 2-0 up with a goal each, but a brief period when we conceded a penalty and hesitated dealing with a loose ball in our box was ruthlessly punished by Leeds to level the scores and force us to share the points.

'It was two key moments in the game that we didn’t take care of, when we didn’t stay calm,' reflected Rosenior. 'Moi Caicedo’s a magnificent player, he’s been top for me, but he makes a poor decision. How the play gets there as well, we made a few poor decisions in terms of how we press in that moment and we give away a penalty.

'The penalty goes in, they hit a few long balls, their energy is up, they pick up a few second balls. The player handballs it, it affects my players in that moment, they think it’s a handball and switch off and don’t clear the ball, they score.

'Then for 25 minutes after that it was wave after wave of attack, but we couldn't find the goal. We have to just make sure we take care of those moments and be professional. I don’t think it’s about reacting to set-backs. You’re always going to have a spell in the game when you’re not on top.

'The ridiculous thing for us is that they’ve managed to score two goals in a five-minute period, when for the other 90 minutes of the game we were by far the better team. We just made poor decisions in key moments.'

There remained positives from the game, with Rosenior seeing plenty that he liked as we took our two-goal lead, although ultimately that only added to his feeling of frustration at the moments which cost us all three points.

'Some of our football in possession, our press, our energy was everything I want to see, and that makes it even more of a bitter pill to swallow, that we haven’t won the game,' he admitted.

'If we can just focus and concentrate for 90 minutes, this team has unbelievable potential, which you saw for probably 90 per cent of the game today. I feel like I already know what I want to work on to improve that, it’s just making sure we get the time to do it.'
