Chelsea injury news: Diego Costa returns to training ahead of MK Dons clash allaying knee injury fears

Chelsea have been handed an injury boost ahead of their fourth round FA Cup showdown against MK Dons on Sunday (31 January) after Diego Costa returned to training on Thursday. The Spain international limped off after 68 minutes during their 1-0 win over Arsenal on Sunday (24 January) with a suspected knee injury, but his return will allay any fears of a serious problem.

According to the London Evening Standard, the former Atletico Madrid striker was pictured by the club's official channel on the training ground with the rest of his teammates suggesting that there was nothing serious. Guus Hiddink will be delighted at his striker's return, as he has been in great form since the Dutchman's arrival at the club, scoring six goals in his last six appearances for the club in all competitions.

Costa was a doubt for the game against Arsenal, in which he scored the winner before his injury, after he suffered a knock during their 3-3 draw against Everton. The former PSV Eindhoven manager had hinted that Costa's injury was not serious following the game against the Gunners, while praising him for his work and contribution during the game despite criticism from Arsene Wenger with regards to the striker's involvement in sending off Per Mertesacker.

"He is focusing on his first job. There are no big conversations [about temperament] but we talk. [I tell him] 'Don't waste any energy which you don't need. You need the energy to put in to what you're good at.' He's focusing on that and finally it's paying off," Hiddink said of Costa, as quoted by ESPN FC. "We'll do some scans but I don't think it's very serious," the Dutch manager added.

Meanwhile, John Terry has backed the Blues to finish in the top four this season following their win over their north London rivals and Hiddink has agreed with his skipper.
