Costa training

Diego Costa took a full part in training with the Chelsea first team yesterday as the likelihood of a move to China dwindled. Press Association Sport understands Costa was involved as his Chelsea team-mates returned following two days off after their English Premier League win at Leicester. Head coach Antonio Conte said the 28-year-old striker was absent from that game with a back problem, which resulted in him missing three days of training last week. Costa had been linked with a mega-money move to Tianjin Quan jian. Chelsea are determined to keep Costa, who has scored 14 goals in 19 matches for the league leaders this season.
