Matic is Premier League proven. He was poor the season before last, but so were the others. Hazard, Costa, Fabregas, etc, were all shadows of themselves.
This season; however, Kante has got all the plaudits, but Matic has also done a very good job and has gone under the radar because what he does often doesn't get noticed.
Matic is a proper holding midfielder. He is the one that sits in front of the back four and snuffs out any opposing attacks for Chelsea, hence why Conte would play either Kante or Fabregas next to Matic. It was very rare you saw a double pivot of Fabregas and Kante, because neither are holding midfielders.
This is why the rumours of Bakayoko going to Chelsea to replace Matic confuses me. Again, Bakayoko is not a holding midfielder, and I honestly feel that Chelsea would struggle without Matic.
However, if that is the case, and Matic is available, then we should buy him.
Like I said, he's premier league proven, has come off the back of winning a premier league title, where he was pivotal, both in his first and third season (2 titles in 3 seasons, not too shabby) and despite what people have been saying, he's actually a good player who would slot right into our team.
Now, I personally don't feel Conte will sell him because of the reasons I spoke about above, however, if he is up for sale, then we're in no position to be saying no to a player like Matic, in my opinion.
