Chelsea legend Ruud Gullit is surprised seeing Juan Mata frozen out.
The midfielder was completely dropped for victory over Fulham yesterday.
"He was one of the best players last year, therefore it's something personal," Gullit told Sky Sports.
"I live in Holland and we watch a lot of games in the Premier League and we've seen a lot of Chelsea games.
"The criticism that most people have in Holland is that with the team and all the names they have, they haven't played good football. They have played very defensively.
"I think they can play much better football than they've shown. It's sometimes too tactical. With the players he has you don't need to be like that. You can be a little bit more adventurous.
"He took that out by not playing Mata. Oscar is a great player, I agree with that, but I'm afraid everything becomes too tactical."
