The Spanish Federation has asked for Diego Costa to travel to Spain to undergo a medical scan even though the Chelsea striker is expected to pull out of the squad due to an injury, according to reports in Spain.

Manager Vicente del Bosque included the striker alongside Cesc Fabregas in his squad for the upcoming games against Ukraine on 27 March and the Netherlands on 31 March to put an end to the controversy over the duo's perceived lack of commitment with the national team, after they missed the two previous games against Belarus and Germany in November with injuries.

But Costa is expected to miss Spain's upcoming games once again after suffering a hamstring injury during the second half of the 3-2 victory over Hull City on Sunday 22 March.

Even though some may question the timing of the injury it looks like this time there is no doubt over the player's injury after he was forced to leave the field with the Blues needing a goal to take the three points.

Mourinho refused to confirm the length of the injury while Spain made an official statement to announce that Costa would undergo a scan in London on Monday morning before making a decision on whether the striker is available for the upcoming internationals.

Earlier on Monday the Spanish football federation called up Malaga striker Juan Miguel Jiménez López Juanmi as a clear sign that Costa was expected to pull out of the squad.

However, Spanish newspaper AS have now claimed that Costa has been told to join the rest of the national team on Monday night in Madrid to undergo a medical scan with the national team doctors.

Some reports claim Spain have forced Costa to make the trip to Spain, while others say Costa made the decision to go to Madrid to show his commitment to the national team and put an end to any negative speculation.
