IF Middlesbrough mean to go ahead with their rumoured plan to sue the Premier League in the High Court, let them beware. They could be falling seriously foul of FIFA. FIFA's rules, however draconian, and perhaps open to challenge in the European Court, specifically state that no affiliate or member of their body may take a case outside its own disciplinary structures. A recent heavy fine and suspension on a Spanish club president, which appears to have gone unchallenged, shows that in such cases FIFA means business. How ironic that Middlesbrough could find consolation at Wembley tomorrow in the FA Cup Final. Should they beat Chelsea, and thus win the first major trophy in their 121-year history, they would also be in line - as a Nationwide First Division club - to participate in next season's Cup Winners' Cup. Would that, could that, staunch the flow of foreign talent from Boro? Might it induce the Brazilians Juninho and Emerson, the Italian Fabrizio Ravanelli, to stay? One doubts it. Emerson has been longing to get away for most of the season; and his form in its last months has been deeply disappointing, as he consistently flatters to deceive. Ravanelli has scored an abundance of goals, but has not really made too many friends. Shortly before that crucial last League game at Leeds, the Boro full-back, Curtis Fleming, made a bitter, astonishing attack on him, stigmatising him - which seemed strange - for going back to Italy for treatment to his injured back, and implying that he would miss the Leeds game. Which he did. Bryan Robson came angrily to the White Feather's defence, insisting that Fabrizio would be on the plane back to England for that game - which he wasn't - and pointing out, aptly enough, that when last Ravenelli had been injured, his treatment in Italy got him fit for the League Cup Final. The one hero among these three foreign stars is beyond doubt Juninho, that wonderful little inside forward - to call him a mere midfielder is surely imprecise - who not only has a colossal talent but has played his heart out for the club in such difficult circumstances. When they could only draw at Leeds he sat on the ground, the very picture of misery, and had to be comforted by Robson. Chelsea, I think, will win this final. They are a much better balanced team, they have their answer to Juninho in another brilliant little Latin, Gianfranco Zola and above all, their morale is bound to be much higher. Behind Zola and a resuscitated Mark Hughes, whose ankle troubles will seemingly not keep him out of the game, plays the elegant Roberto Di Matteo, who has been let off the leash at Chelsea, able to break into attack and score goals, by sharp contrast with the way he was restrained at Lazio. This has, alas, been a mediocre Premier League season. Manchester United did at least go out with something of a flourish beating West Ham 2-0 at Old Trafford, but they looked anything but scintillating in their two previous draws there, against Middlesbrough, when their defence was a colander, and Newcastle. The Magpies boldly took that second vital Premier League place, and thus a Champions' League place, thrashing poor Nottingham Forest 5-0. Kenny Dalglish does at last seem to be getting the balance right and his new signings should prove significant.
