When someone is drawing an extra man in this way it is up to the other members of the team to utilise this additional space. Nearly everything we do goes through Adam so when the team continue feeding it to him even though he is the marked man just means that he has to do what he can. Ramirez wasn't the only one. Morgan, Cork and Davis should have been taking advantage of the extra space but just kept feeding it to Lallana.
Yes he lost possession a lot but if you have the ball a lot you will lose possession more. Ramirez just tends to do 'show the defender the eyes' passes assuming that his teammates will have read it is going in a different occasion. He did this 2 or 3 times on the right hand side of the box, moving as if he was going to take on the Chelsea player and burst into the box but instead passing it to Chambers. Problem being all 3 times Chambers had to change direction towards the sideline because the passes were too wide.
