Sunday will be the first time Diego Costa and Chris Smalling have clashed in club football - but the Manchester United defender had the upper hand when the pair met on the international stage. Striker Costa was suspended for the 0-0 draw between Chelsea and Manchester United at Old Trafford in December, and missed both fixtures between the clubs last season with hamstring injuries.However, he did come up against Smalling when Spain hosted England in a friendly last November. Spain eventually ran out 2-0 winners, but the game was goalless when Costa was substituted on 64 minutes. This will be Costas first-ever game against Manchester United. Hell hope it goes better than his previous encounter with Louis van Gaal - Costa and Spain were on the end of a 5-1 group stage defeat to the Netherlands at the 2014 World Cup.However, Costa has rediscovered some good form and has flourished under interim boss Guus Hiddink with five goals in six Premier League appearances under the Dutchman. That is a marked improvement on his goal ratio under Jose Mourinho this season.
