RADIO CLIVE'S FIVE: NORWICH V CHELSEA

Throughout the season former player Clive Walker provides radio and TV commentary on Chelsea's games. Here he selects five aspects from the trip to East Anglia that caught his eye…

It is often the attention to fine detail by Jose Mourinho we talk about and when Chelsea won the toss before kick-off they changed ends. The sun in the first half seemed to cause Norwich goalie John Ruddy problems which doesn't happen very often these days because of the size of many of the stadiums. Carrow Road is obviously one where it can have an effect so it was a distinct advantage to us first half.

The selection of Demba Ba as striker may have been partly due to rotation of players and using the full capacity of our squad, but Jose Mourinho probably looked at Norwich's two centre-backs, saw their physical presence and decided a fired-up Ba was going to give as good as he got. We put some long balls forward to him more than we did on top of the goalkeeper, and back to goal, Ba is facing the sun as well. He still caused problems for the centre-backs and with the early goal, he did ever so well to get hold of it and lay it off to Oscar. That is not particularly our style but on that occasion it worked well.

In the second half Norwich changed their attitude. They were 1-0 down and in need of a goal and they tried to engage us a little more in the middle of the park. We ran it first-half in midfield but in the second half they raised their tempo and work rate, not dominating but causing us problems.

After Norwich equalised, we went three at the back when Ashley Cole came off and it was a positive move. Norwich would have thought 'we are under pressure now', they wouldn't have been thinking when we get the ball we must get into wide positions on that flank. It was too late in the game for them to change like that. Mentally it was a great move by Mourinho. Norwich were thinking we are going to have to be on our toes defensively so whatever Chelsea did at the back wasn't going to concern them.

In the final 10 minutes Chelsea showed that bit of extra quality that wins you games. For the second goal people will say Alexander Tettey's touch was poor, and that John Ruddy should have saved it, but Eden Hazard's shot was bang on target, a good contact, and what can you say about the Willian goal apart from terrific - the icing on the cake, and by then the momentum was with us.
