According to the news of the Spanish newspaper Sport, Barcelona are pushing all possibilities to add N'Golo Kante, whose contract with Chelsea will expire at the end of the season. If this transfer takes place, Barcelona will strengthen its power. If Barcelona wants to buy this player, they definitely will. Because a football player like Kante wants to play in a team like Barcelona.
Whilst it is good for Kante if this news is true, it is almost certain that Chelsea do not want him any longer once his current contract expires, so to move to Barcelona won't be a bad choice at all, they (Barcelona) aren't at their best just yet, but they are resurgent and the name Barcelona will always stand out.
Having said that, on the other hand, whilst i think Kante is still a very brilliant footballer, i expected Barcelona to go for someone quite younger to replace Busquets, except they see Kante as a short term option, and if they prolly aren't going to pay any transfer fee for him, because i guess he would be a free agent once his contract expires pretty soon, if that be the case then it might be a good short term move for Barcelona.
