Roberto Pereyra may miss rest of season with knee injury

Watford have been rocked after record £13 million signing Roberto Pereyra was ruled out for four months – and he could miss the rest of the season.
The Argentine playmaker damaged the meniscus – cartilage which acts as a shock absorber between bones – in his left knee during the Hornets' 2-0 defeat at
Manchester City last week.
Manager Walter Mazzarri had initially feared Pereyra would be out until March – but after scans, the latest medical bulletin at Vicarage Road suggests he may not feature again for the rest of the season.
