Real Madrid's world-record signing Gareth Bale is nowhere near ready to complete 90 minutes ahead of his return to the Spanish capital, according to Wales boss Chris Coleman.
Bale came on as a substitute for Wales last night in his first competitive action of the campaign, playing 32 minutes in a 3-0 defeat to Serbia in World Cup qualifying.
The forward has been struggling in the past two months with groin and foot problems, with Coleman deciding the winger was not fit enough to start either of his side's qualifiers against Macedonia and Serbia this week.
Coleman has insisted that Madrid will need to use the same caution in Bale's first few weeks at the Bernabeu, describing his current fitness levels as "dangerous" ahead of his potential debut in La Liga this weekend.
He told Sky Sports: "If he starts Saturday, he will not finish the game. I would be amazed if he does. We have looked at him in these 10 days and he is nowhere near ready for 90 minutes even if Spanish football is slower.
"He may start, but he won't finish the game. He may get 45 minutes, I don't know, but he will feel better in himself after 30 minutes here. But he has only had four training sessions in two months which is dangerous.
"He played 30 minutes but after 15 minutes he looked tired, but he has only had four training sessions, so you will not get what you normally get."
Madrid coach Carlo Ancelotti will get his first chance to assess the former Tottenham Hotspur talisman in training this week, ahead of Real's trip to Villareal on Saturday evening.
Bale faces a fight to earn a place in Madrid's starting XI this weekend regardless of injury, with Ancelotti's side starting their league campaign with three successive wins.
