Raul Jimenez's injury could have a galvanising effect on Wolves, according to Chelsea boss Frank Lampard.
Striker Jimenez is recovering from surgery on a fractured skull suffered in a sickening aerial clash with Arsenal’s David Luiz in late November.
Lampard was part of the Chelsea team on the day goalkeeper Petr Cech suffered a similar injury to the Wolves striker against Reading in 2006.
Cech had surgery on a depressed fractured skull after being hit on the head by Reading midfielder Stephen Hunt’s knee and was sidelined for three months.
