Diego Costa flooring legendary Chelsea physio Billy McCulloch with boxing combo is priceless

Diego Costa is on the verge of completing a shock return to England's top flight this summer, which means we all get to enjoy his wild antics in the coming months.

The 33-year-old forward will undergo a medical at Premier League outfit Wolves on Tuesday, according to reports.

He is, of course, most well known for his three-year spell at Chelsea. He joined the Blues from Atletico Madrid in 2014 and in the coming years, displayed his volatile behaviour, both on and off the pitch.

Given that temper, it should come as no surprise the Spaniard had a 'boxing match' in training - and won.

Chelsea defender John Terry shared the below footage from Chelsea's pre-season tour, with Costa showcasing some breathtaking moves against legendary physio Billy 'Rocky' McCulloch.

Check that brilliant footage out below.

The tweet was captioned: "@diegocosta Vs Billy ( AKA ) Rocky Pre season 2014/15 After this I knew we would win the league. What a Legend. I'm crying watching this."

Both men size the other up to start with before McCulloch reacted to Costa's taunting. Costa then backed away from his foe before levelling him with a few shots which McCulloch attempted to get up from.

'Rocky' was spent however and after getting up once again, he went to ground.

The exchange was all in good fun and both men embraced at the end as the rest of the squad gave a round of applause.

Former Chelsea captain Terry was asked about his thoughts on Costa in the replies and 'JT' was full of love.

He said: "Genuinely a top guy. I loved him because he gave everything, every single day for our club. He cared and was an unbelievable player."

During the Brazilian's spell in England, he lifted two Premier League titles and the Carabao Cup.
