Football works in funny ways - just ask Arjen Robben. The Holland international played with distinction for Chelsea between 2004 and 2007, before upping sticks and moving to Real Madrid.
Now the winger plies his trade for Bayern Munich and stands in the West Londoners' path as they search for a first UEFA Champions League title on May 19.
"I had a great time at Chelsea and I'm really happy they reached the final," Robben said.
"I saw their semi-final against Barcelona and they did well in a defensive capacity - you could say they parked the bus in their own area.
"But I have to disappoint them - because they are not going to win it!"
Robben has history of hurting former teams - just ask Jose Mourinho and Real Madrid.
The winger did not enjoy the best of times at the Santiago Bernabeu and was promptly shipped off to Bayern for an estimated 25million euros in 2009.
Three years on, he returned to Madrid for the recent Champions League semi-final second leg and promptly kicked them out of the competition.
Robben converted a 27th-minute penalty to stunt the hosts' early dominance that was epitomised by Cristiano Ronaldo's double strike.
Bayern held out and triumphed on penalties, with Manuel Neuer and Bastian Schweinsteiger the shoot-out heroes.
"At half-time we all spoke up and said to each other that we could do this," Robben said.
"We realised there were parts of the game we controlled and we looked the better team.
"Having said that, we also knew we had to take care because Madrid have such great quality up front.
"Before extra-time started we had a feeling we had a slight advantage.
"We felt that some of their players were tired after the effort they put in.
"I think our physical condition is one of our strengths and we proved that by showing we can play for 120 minutes or more.
"I am very proud of my team, because when you start a game like this and after 14 minutes you are 2-0 down, then you have to be mentally strong to cope with it and recover from it.
"I think, overall, the rest of the game, we played some really good football.
"In the end, I think we can say it is deserved."
Robben will be hoping for a similarly happy ending when he comes up against the Blues on May 19.
Bayern head into the match as slight favourites and are boosted by the fact the final is played at their home ground, the Allianz Arena.
"To be in a home final is almost indescribable," Robben said.
"It's so great, especially for those who have been connected with the club for so long."
There had been suggestions the final would be Robben's last for Bayern, with interest from some of Europe's giants.
However, the 28-year-old has signalled his intention to remain with Bayern for at least the next three seasons.
