If you look for a definition of a 'love-hate relationship' online, do not be surprised if you see a picture of Rio Ferdinand and Ole Gunnar Solskjaer together.
Topsy-turvy has been the name of the game ever since the pair first met. After Ferdinand completed his record-breaking transfer to Manchester United from Leeds in 2003, Solskjaer was the first to rip into him.
'30mill? Really? Wow' shouted the Norwegian when Ferdinand took a bad touch in training. The comment was not meant to be harmful to his team-mate, but now the shoe is on the other foot.
