Can difinitely slowed us down but considering it's his first PL start I don't really blame him since the other lads are used to playing week in, week out. He needs a run of regular games under his belt to start showing his best form, anyway he is only 22 so it's not surprising he found it difficult playing tonight.
I do think the occasion got to the players, the game has been drummed up all week and we were the clear favourites. Obviously Mourinho's tactics to frustrate us and quieten the crowd worked for the most part. But in the first half we were really poor, lots of bad decision making and general sloppiness.
What about the Sturridge conundrum? I feel like he disrupts the flow and balance of the squad, he just can't do what Klopp likes i.e. pressing from the front. Once Lallana came on for Sturridge we looked 10x better and far more threatening, Firmino kept winning and knicking balls which in turn made it easier for the rest of the team to push up and get a counter attack going on. But then again in and around the box he is so clinical and capable of magic, I wouldn't be surprised if he wanted to leave at the end of the season to play regular football.
All in all, 1 point isn't bad, I'd take the same next time at OT. Main thing is to bounce back and win this upcoming weekend.
