Pictured above at logger-heads during Chelsea's Champions League defeat to Atletico Madrid, John Terry and Diego Costa are now teammates.
Costa's €40 million switch to Chelsea was confirmed earlier this week, unveiled by the club on Tuesday.
Terry gave his thoughts on the blockbuster transfer yesterday, even commenting on the disagreement he had with Costa during the semi-final.
He told Chelsea's website that Costa's refusal to back down from the argument, showed that he is not a player who the opposition can intimidate.
"‘I think everyone remembers the square-up we had in the first 10 minutes of the first leg of our semi-final game against Atletico Madrid last season, after which I thought, “Fair play”.
‘He holds the ball up very well, he has got great movement and he is really physical, but he is very clever with his strength and the way he uses his body. I think he could be a very good signing for us.’
Costa was prolific for Atletico Madrid last season, firing them to the La Liga title.
His abrasiveness up front, as well as his skill, will be crucial for a Chelsea side which has lacked swagger in the striking department ever since Didier Drogba left.
Many a Premier League defender will try to rattle Costa, who has a reputation for giving it back with the best of them, but Terry is clearly confident it will not work - it certainly did not when he tried it.
