I wouldn't say his season is average, but he's been playing on his own for some time and today it was an exaggeration. It's not a surprise that his best action (probably the only good one today) was that run where he dribbled half of their team. He relied everything on his dribble and he didn't try anything different, and it's not the first time it happens, nor the second.
Many times we play slow football against a parked bus and he has no chance of doing anything, so he has an excuse for me. But today there was room to play faster and take profit of spaces, and he ruined many actions by keeping the ball too much, or facing a wall of defenders when a fast and simple pass to a more uncongested zone would have been much more productive.
He needs to read games and situations better and use some different tools, and he has showed before that he's able to do it, even when we are shit as a team. It's true he's played a lot of games, but he didn't look tired in that run where he nearly scored, or missing his wife or anything. And he was pressing at the end of the match with energy, so I don't buy any excuses today. He's a massive talent and he can play much better than this.
