I don't think there's any delusion about it really, we know we've been helped a lot with our loan signings. With that said, I think their impact has been overstated. Deulofeu has been injured for a large chunk of the season and for nearly half this season, Lukaku was either injured or playing terribly. Barry has been a big plus.
The impression I get is Barry and Deulofeu might be able to stay next season, Lukaku it's very unlikely.
