"With respect to Aaron Ramsey - I do not know what to expect," said Dutch fitness guru Raymond Verheijen to BBC Radio earlier this week ahead of a continued comeback for the Welshman on Saturday, April 12 against Wigan Athletic in the FA Cup semifinal at Wembley Stadium.
Ramsey was named amongst Arsene Wenger's substitutes last week but was only selected for 25 minutes of action during the unsuccessful top four dogfight with Everton, a game the Gunners lost 3-0.
The box-to-box midfielder, who was in sensational form for the first half of the season, has endured a complicated campaign. He suffered a thigh muscle strain in late December yet has been sidelined for four months having been set back numerous times.
"If you look at his rehab it is yet again a complete disaster," said Verheijen.
"He pulled his muscle in late December and normally you are out for four or five weeks but after three setbacks his rehab took more than three months."
Verheijen advises Arsenal that a cautious approach to Ramsey's comeback would be beneficial for the player's short-term and long-term fitness plan, otherwise he may strain the muscle again.
"I think Arsenal should be careful with Aaron otherwise he'll suffer his fourth setback," he commented, before adding that fitness coaching throughout the country is behind the times: "It is decades behind the continent in terms of fitness. It's not nice to hear but the problem needs to be addressed."
