I voted for Clyne. Ivanovic is also great but this season whilst he has been excellent defensively I don't think he has done as much going forward as he has done in previous seasons. I think that Clyne has done a good job in both parts of playing in the RB position (attack and defence).
Probably. Part of the issue with Ivanovic is that Mourinho has coached the attacking side of his game out of him to a degree. There are so many matches, especially in the latter half of the season, where Chelsea have simply parked the bus, so it's unsurprising really.
The restricted Ivanovic has scored 4 goals and got 5 assists this season compared to 2 goals and 0 assists for Clyne. And Ivanovic has only ever scored more in a season once, by just 1 goal too.
I wouldn't miss a chance to criticise Mourinho but that's an odd criticism to lay at him. Ivanovic looks better than he ever has going forward in the last 18 months or so.
