You have to consider the upcoming GE changes as well, when you create your Training shedule for Timo.
I would prefer the following skillset in order to have good chances against the op Look Inside Tactic:
IS: 9 / ID 13 / RB 11 / SB 11
Start with ID Training to 13 and give him SB Training as long as he will reach his cap.
His salary will be at approx. 25 k to 26 k, when he will be ready. Due to his low Pot you will not be able to train him any further than that.
Well, it might happen that he will get some extra pops, when you will train SB (trains ID and RB as well). If that will happen, Skillset will look a bit different at the end, which wouldn´t be that good...
To be honest, I wouldn´t train that guy anyway. You should try to sell him and buy a younger Player with more Pot.
