Arsenal manager Arsene Wenger admits he doesn't know what he'll do when he retires from the game and has spent some time pondering how his old foe Sir Alex Ferguson has filled his days since quitting as Manchester United boss.
Wenger will take his Arsenal side to Old Trafford on Sunday, returning to the scene of so many epic battles with Ferguson during their enduring rivalry, with the Gunners boss maybe even missing the duels he used to share with the Scottish tactician.
"I sometimes wonder what is he doing with his days," Wenger told reporters as he was asked about Ferguson. "I have to say he looks very happy in his retirement.
"He is lucky because he is interested in horses. When he gets up in the morning, he can go to his horses and watch them in training, so that must be great for him.
"What would I do if I was retired? I love horses as well, but I don't go to races. I like to ride horses because I was once a farmer, but my back would not take riding anymore. Maybe I will just watch a lot of football matches when I retire."
For Wenger to be even considering retirement plans in public is something of a change of direction for the 65-year-old Frenchman, who has always fended off questions about when he might quit the Arsenal role he has held since September 1996.
Yet Ferguson won eight major trophies from the age of 65 to his eventual departure at the age of 71 and the Arsenal boss has been reflecting on what he needs to do to push his side closer to a title push next season.
Arsenal will secure a top three finish if they beat Manchester United on Sunday, but they find themselves a long way behind champions Chelsea and Wenger accepts improvements are needed.
"We have that feeling in the squad that we are getting close to a title challenge, but we have to go and prove that next season," Wenger added.
"Everyone can see that we are behind Chelsea. They made a big leap this year because they've lost just two games and they never had a really bad run. So you must say that is a massive leap to what they did last season.
"Also, they had good cohesion at the back and Diego Costa was a big signing for them. He and Cesc Fabregas gave them a big boost and I think you feel the strength of the team when you play against them.
"What will happen next season is unclear. We don't know how strong Man City and Man United will be when we get to the end of the transfer window. You expect them to respond, as well as Liverpool, so we can't say what standard will be needed next season.
"People are always having good ideas of where we can strengthen, but when you look at who it may be to come in, it's much more difficult.
"You can always look at possible areas where you can strengthen but sometimes in your own team the cohesion is important as well. And that is linked to the type of players that play together.
"We spoke about Chelsea. They have a stable defence that has played together for two or three years now and they conceded less goals than the other teams. That is no coincidence. Every team needs a good spine, but change is not always the answer to everything."
